Can we do this? (aka The DIY Cruise Control Thread)

[CTScott]

I finally found the info on the correct terminal with the waterproof sleeve for the ECM connection. It is the female terminal with the waterproof sleeve and 500mm of wire attached. It is intended to be a repair item for a damaged terminal, where the tech just has to splice the wire, rather than having to deal with attaching the wire properly to the terminal.

The part number is: 82998-24250

Hi All. I have been lurking, reading through the 2 posts about the DIY cruise control on and off for a while now. I have an 09 Yaris Sedan, M/T. I took off the panels on the top and bottom of the steering column and have verified that yes, my car also does not have the brown and the blue wires coming from the plug. Only the black ground for the horn. It does have the indicator lights on the dash to the right of the speedometer. The "CC on" light and the "set" light.

I have been looking over the 2007 yaris factory repair manuals. I have been following along with everything you said and it all looks good to me.

CTScott, I had a few questions for you that I couldn't find the answer for anywhere in any of the close to 40 pages of both the posts.

First, where are you finding the OEM part numbers? Like for the interior panels for instance. I found a lot of part numbers for connectors at the end of the wiring diagrams section of the factory manual, but could not find a toyota OEM parts diagram anywhere.

Second, I was thinking of trying to get this ECM connection with the wire already attached that I have quoted above from you. Then I was thinking about it and from what you have, I wasn't sure if this was somehow a terminal that plugged into pin 40 on connector A21 or if this part was the entire A21 connector with about 40 or 50 - 500mm lengths of wire coming from all the pins. If it were the latter, I wouldn't want to get it, because I am not about to cut and splice all the rest of the existing, in-place, wires just so I could get that one wire from pin 40 waterproofed. So I guess the question summed up is: is part number 82998-24250 one wire with a connector or A21 with a lot of wires coming out of it?

The wiring diagram manual has part number 90980–12462 for A21 and TRD sparks has a higher MSRP for this than they do for part number 82998-24250.

Also, I looked up under the dash today and found a white two prong plug, with a blue and a black wire going to it. This plug was taped up against the wiring harness and was not plugged in to anything. It looks to me like its the right plug for the Cruise Control Clutch Switch according the the wiring manual.

I am planning on doing the 2 switch method, but I have yet to buy any of the switches, resistors, Cruise Control Clutch Switch, or the waterproof connector for the ECM.

Another thing I was wondering, if I wouldn't have access to what you are using to get OEM part numbers. On the sedan, there is a small panel to the right of the dimmer switch. I want to put my switches there. Is there any way you could find out what the part number is for that panel, so I could try to order another one?

Full of questions here. If I go to the dealer with these part numbers, will they just be able to order them for me? Or should I try to go through TRDSparks or somewhere online? It seems like, at least for the older toyotas I've had, that the dealer cannot get a lot of items like interior panels and the like. This is my first new car, so maybe it's different, I'm not sure. I was trying to avoid paying shipping costs, they seem a little high at TRDsparks and I always hate waiting heh. But I do get annoyed when they ask for a VIN number at the dealer too.

Overall, I'd like to say thanks to everyone who contributed to these posts. I was planning on buying that aftermarket kit (which I originally thought was the OEM CC) from TRDSparks for like $200 before I found this.

The service manuals don't list part numbers. The part numbers come from the Toyota EPC (electronic parts catalog). You can access it online at Toyodiy.com

82998-24250 is a single wire with the terminal and waterproof plug for connecting to the ECM.

If the cover you are looking for the PN for is the one where the power mirror switch would be then the PN is: 55547-28010-B1

For ordering the parts, you are probably better off going through TRDsparks. The dealer prices will be higher, and they will probably have to order most of the parts, so you may not save any time.
