AWoolford 0 Posted January 28 Share Posted January 28 Greetings folks. Just joined today because I am trying to fit a cruise control to my Yaris 2017 SE. It is middle eastern spec in the UAE and I obtained a kit from the US via Amazon. Sadly the connector inside the steering wheel is a 10-pin affair, not a 3 pin as per all the guides. Furthermore, on unplugging the 10-pin connector, I found there is only 1 pin actually fitted to the spiral loom, (pin 5), which apparently goes only to the earth tab on the airbag. Mechanically, the cc arm fits and there is a pop-out panel on the steering wheel for it. So to proceed further, I suppose I will need to replace the spiral loom with one which has the wiring for the cruise control and, most likely, run a new wire from the other end under the steering column back to the ECU. Does anyone have any experience of doing this and what part number would I need for the correct Spiral Loom? Any help gratefully appreciated. Quote Link to post Share on other sites
flash22 655 Posted January 28 Share Posted January 28 What size engine and is a UAE car or an import You will need a different clock spring aka a spiral cable, it must be a very basic car not to even have audio controls Quote Link to post Share on other sites
AWoolford 0 Posted January 29 Author Share Posted January 29 It is a 2017 Yaris SE (Sorry for the typo in the title that said 2016). It is a UAE car, not imported. According to this: https://www.vindecoderz.com/EN/check-lookup/MR2K19F39H1026946 ...it is a 1300CC 16valve DOHC (1NRFE) engine. I attach some pics below which might help. The android audio system shown now is aftermarket but there were no audio controls on the steering column. I have shown the instrument cluster with all lights illuminated after turning on ignition. There does not seem to be a CC lamp, so maybe the ECU doesn't support it either? I have a chassis number if that would help identify it. MR2K19F39H1026946 With that said, the official toyota.com website doesn't seem to think this is a valid vin number, despite the other site above having found it.

flash22 655 Posted January 29 Share Posted January 29 Toyota.com is the US site as it is a UAE car its comes under Asia/Japan I put you vin through the General EPC (non-specific region) Here's some info................. Model code - NSP150L-AHXRKV Build date - 06/2017 Engine - 1NRFE Colour - 040 Destination - GCC (Gulf Corporation Council) - built in Indonesia, The model mark is R, and it's classed as a category A I will have to look more into GCC spec Edit. Cruise was part of the e-sport package - can't find any good images of the clock springs aka spiral cable but there are only 2 types The E-sport package one is - 84307-0D130 Audio controls - 84250-0D090-C0 there are also a Brunei spec audio controls Audio controls - 84250-0D200-C0 1 Quote Link to post Share on other sites
AWoolford 0 Posted January 29 Author Share Posted January 29 Many thanks for that info. I note from googling the part numbers that the 84307 Spiral cable includes a "steering sensor". Do you know what that is for? The 84306 alternative comes without. You mention the audio controls as well... Just as an aside - I would think there would need to be an audio loom going from under the steering wheel to the audio panel. I'm pretty sure the aftermarket stuff would interface to it if the loom is there. If it's not too much trouble, do you have any details of that loom as well please? Going back to the cruise control, It might be possible to find an e-sport out here in a scrapyard and strip the relevant parts. Is it worth replacing the ECU as well do you think, or is that likely to cause issues with other systems? Again, I am wondering about the ECU loom for the cruise control is needed? Sorry for all the questions. Really appreciate your time. Quote Link to post Share on other sites
flash22 655 Posted January 29 Share Posted January 29 The sensor is the steering angle sensor the only 2 spiral cables listed for your vin are 84307-0D120 84307-0D130 The Chinese built cars don't have airbags the audio controls use 3 wires A, B and ground for and aftermarket radio you will need an interface adapter re, wiring it is easier if you make your own wiring to suit, using the parts from a scrap car as the those cables are integrated in to the dashboard loom how many wires do you have at that plug ? Pins 1 and 2 are for cruise control These are the pin numbers for that connector (As viewed from the front of the connector) ps. the single wire to the airbag is for the horn Quote Link to post Share on other sites
AWoolford 0 Posted January 29 Author Share Posted January 29 Thanks for the pin outs. I take it the pale pink wire is pin 1 and the brown one next to it in your photo is pin 2. I'll have to look tomorrow as my gf is using it right now. Will post a pic here. Cheers Quote Link to post Share on other sites
flash22 655 Posted January 30 Share Posted January 30 In the picture I edited, The bottom row is 1-6 (Left to right) Quote Link to post Share on other sites
AWoolford 0 Posted January 30 Author Share Posted January 30 Ah great diagram thank you. Could you clarify your comment "bottom row 1-6 left to right". I don't follow your meaning there, sorry. Quote Link to post Share on other sites
Bos 6 Posted January 30 Share Posted January 30 I think you will find that the photo of the connector is upside down compared to the diagram. 1 Quote Link to post Share on other sites
AWoolford 0 Posted January 30 Author Share Posted January 30 Oh I see what you mean. I had assumed the line drawing of the connector was looking towards the pins rather than where the wires entered in the photo. Sorry I didn't get around to opening the steering column today to take a comparison pic... will try again tomorrow. Quote Link to post Share on other sites
flash22 655 Posted January 30 Share Posted January 30 The line drawing is the front of the connector (not the wire side) the picture - the connector is upside down Quote Link to post Share on other sites
AWoolford 0 Posted January 30 Author Share Posted January 30 Got it thanks. I will lie upside down with my head in the footwell so it looks the right way up 😜 Quote Link to post Share on other sites

AWoolford 0 Posted January 31 Author Share Posted January 31 Okay here are the pics of that connector... The connector looks different to yours though and it is next to a yellow one with two brown wires which I assume is for the airbag. As you can see there are no pins in the actual socket that it plugs into. Quote Link to post Share on other sites
AWoolford 0 Posted January 31 Author Share Posted January 31 Correction there is one pin going to that grey wire in the top row which I guess is for the horn. Quote Link to post Share on other sites
flash22 655 Posted January 31 Share Posted January 31 That's correct your car looks to be pre wired for cruise and audio controls As yours is a gcc car things like wiring colours can be different compared to European cars The airbag has its own connector (usually a yellow locking type connector) The socket is part of the spiral cable Quote Link to post Share on other sites
AWoolford 0 Posted January 31 Author Share Posted January 31 Good news then... I'll try to get hold of the spiral loom. Thanks so much for the guidance, I'll post progress here. Quote Link to post Share on other sites
flash22 655 Posted January 31 Share Posted January 31 If you get a used one, take it off care fully tape it or cable tie it in place (wheels and steering wheel straight) And of course disconnect the Battery for a minimum of 15 mins you can also check if the cruise works by shorting pins 1 and 2 this should put the Cruise control light on Quote Link to post Share on other sites
AWoolford 0 Posted January 31 Author Share Posted January 31 Yes I'll be careful thanks. I'm not convinced there is a cruise control light as I didn't see one light up during the lamp check (my first photo in my original post). I'll give it a go though. Quote Link to post Share on other sites

I got the same car, year and I am from the same region, so any updates regarding finding a solution to install the cruise control will be MUCH appreciated Quote Link to post Share on other sites
