2012 Texas Built Single Cab Cruise Control

Project complete.

1. Wanted to add cruise control.
2. Read the forum threads here and Toyota Nation
3. Bought OEM stalk, connecting wire, and side cover.
4. Installed all.
5. No Joy.
6. My truck is a "non-prewired Tacoma" for cruise control.
7. More research and found a company called Rostra.
8. They sell a complete kit for "non-prewired Tacomas".
9. I don't need a whole kit.
10. Ah ha...Rostra sells a prefab wiring kit for non-prewired Tacomas.
11. Had to go through a distributor to order: Brandon Distributing
12. Costs about $12.00 and has the wires for Cruise panel light, cruise switch, ground wire and another wire if you have manual tranny. Some cusioning material and some wire ties.
13. Downside...shipping was like $15.00
14. Wires have the correct clockspring terminals done very nicely.
15. Instructions are on Rostra website as a PDF file.
16. Downside...much of the trim covers on the instrument panel must be removed. Do a search on installing OEM fog lights for some nice pictures on how to remove most panels. They actually came off pretty easy. Just don't force anything or break a clasp.
17. Followed the Rostra/TN/TW instructional information.
18. Ops check good.
19. Mission accomplished.
20. Cruise is now my latest mod.

A big thanks to Tacoma World, Tacoma Nation, the people at Rostra and Brandon.

 

I am curious. What did have to pay for the side cover?

 

$4 0R $5 Dollars and it fit perfect. P/N 45186-0C020-B0. They changed the steering wheel in 2012.

 

question for ebby, can you tell me exactly were you placed the 4 wires from rostra? i'm confused about were to mount them? or if anyone else can answer?

 

your welcome

 

One is a ground.
One is power to the cruise switch
One is power to the cruise indicator lamp
One is to be used if you have a standard transmission

What I did was download complete instructions from the Rostra website. It's a pdf document .

To wire the cruise lamp on the panel requires the removal of several panels on the dash. A lot of work but worth it for a complete install. My motivation for buying the Rostra kit was for the correct clockspring connectors. I wasn't about to try sticking wires in theconnectors and using tape to secure.

There are lots of good photos from other projects to help with the removal of panels. Good luck with your project.

 

Ebby, how do you know if your truck is prewired or not? Were previous models prewired?

 

I bought the cruise stalk, installed it and it didnt work. When the covers off your steering wheel look for the S8 plug towards the bottom of the column. If you only see a green wire then you are not wired for cruise.

 

Is this part required or can you mod your side panel by making your own hole? I thinking the CC kit come with a template to do this but not sure.

 

guess it depends on which kit you buy. if you buy the rostra kit, it comes with the template. then you would need the right drill bit for the template. i went oem cc and brought the steering cover. sure is nice having cruise and real wipers!

 

I attempted to install today and got mostly done. I installed the hardware and ran the wires I got from the Rostra kit. My truck is not prewired for cruise control and I have one thing left:

I got really confused what to do with the wires from the clutch disengage switch and what wires to use the t-taps on. I have everything connected on the passenger side and the steering column, but I just have no idea how to connect everything into the junction box. Ideas or experience?

 

you will have two wires coming out of the clutch switch, one wire goes to the lite green wire in your junction box, which is left of the steering wheel. just tap into that one. the other wire goes to the ecm, if you have 2trfe motor. you would use pin 21 on ecm. if you have 1grfe motor, you wire goes into ecm pin 27. hth

 

Okay, thanks. I have one purple wire tapped into the lite green wire in the junction box.

The other purple wire gets mated to the blue wire, right? Should I clip the existing connector on the blue wire so I can connect it with the purple wire?

EDIT: Clipping the blue wire to connect it with the other purple wire worked. I have no cruise light on the dash, so I can't tell if it's on or not, but the cruise control works just fine!

 

Got my CC kit today. Stopped by Toyota and they want $130 to installed. I have a Texas made Tacoma made in May 2012 Single cab with 2.7. So I don't think its prewired cause Ebby says his was not. Think 130 is fair. They said it would take 2 hours. I don't want to tackle the job or should I get another mechanic price. I would like to stick with Toyota since work would be backed up.

 

go 4 it. if there backing there work. i'm sure sure you could get it done alittle cheaper. i recently did mine, its not that hard.

 

Thanks for your replies. Think I will do that for I will probably set off the air bag and break something LOL

 

It's not that hard to do it yourself. Rostra has pretty easy instructions here. Save yourself $130. I took my time and double checked everything and it took me around four hours.

But if you're not comfortable with taking things apart or basic wiring, it may be best for you to have someone do it.

 

So the cruise control mod worked for about three weeks before I discovered it doesn't work anymore. Tore into the area around the junction box again and found all connections and splices good. Grounding it good.

Is there a fuse I can check somewhere for the CC? Anyone else's randomly stop working?

EDIT: I discovered a loose connection, so I reconnected it and took it for a test drive around my neighborhood at 15mph, didn't work. Going to the airport on the Interstate today, worked fine. Maybe some sort of minimum effective speed or some other rediculousness.

 

Hi Terry, I was wondering if you could help me, I'm doing some research before I buy the parts to install the CC. I've checked the wiring in my truck (2012 A/C with 4 cyl and manual trans) and it looks like I have the wiring from the ECM to the steering wheel, my question is there is already a wire in pin 21 at the ECM (blue with a black tracer), I would assume that this is for the clutch however I cannot locate the clutch switch connector. What do you think?

 

Thought i would revive this thread as im doing the cruise install on my truck. So I tried to buy the rostra wiring kit for non-prewired tacomas and was informed the price on just the harnes has jumped up to $70 for a couple of wires. Some of you lucky few have been able to aquire the same harness through brandon distributing for $11 and now those days are over thanks to rostra.

Since I refuse to pay $70 for a couple of wires, does anyone know the correct size wires and type of terminal needed to insert in the ecu plug connectors?
