Truspeed wire location

[villestrip]

I have a Truspeed speedo correction box and I'm having a heck of a time locating the black/grey wire to splice in to. Supposedly it is at the ABS connector under the hod. Does anyone have a picture of it? Thanks

Anyone????

No photo, but it should be in the connector near the wiper motor.

More info- should be in connector C135 (ABS module) pin 21 located on the ABS control module. According to the drawing I have, it goes into the wiper motor harness pin 4, as well as the 4x4 control module pin 3 and the radio harness pin 14. It is circuit 679.

Good Luck!

I'm having difficulties locating this wire as well... I pulled my air box and battery out on Saturday thinking it would be at the abs unit (behind driver side headlight), no go.. I found the detailed instructions online somewhere with pictures detailing the procedure but you really cant figure out where they unplug the wiring harness that has the black/gray from..
I must have starred at the engine bay for 30 minutes waiting for this wire to jump out at me.. I even went and picked up a Haynes repair manual, that was even more useless than my daughters Dora the explorer coloring book, LOL.

So if someone has a nice picture of the right side of the engine bay, with maybe a BIG arrow pointing to the harness to unplug, that would be awesome!!

Thanks!

UPDATE:
I just located the wire that we need to tap into. When I had everything apart, I found the ABS unit I didn't realize that this bunch of wires that run along side of the fender wall/splash guard were it.
Follow the Wizards instruction as he is taping into the same black/gray wire.

Primetime did you get yours installed? When you calibrated the speedo did you use the charts to calculate the amount of turns or did you use the GPS to set the truspeed?

[primetime1267]

Mine is about perfect, it is off by like 3/4 to a mile off. I'm satisfied to say the least. Use their charts to get you in range and then do 1/4 turns .. use a true gps and a cell phone app gps. I think my truck ahifts better now also, even though people say it doesn't effect it, it did for me.

Sorry for all the questions but which chart did you use? The tire size chart or the gear ratio chart. Nice truck by the way.

[primetime1267]

I used the tire chart since i have stock gears. Thanks !! I love the truck so far.
