i have the truspeed calibrator but i dont know where the abs controller is. the instructions say that it is either under the battery box or on the drivers side fender well.

i see all the plugs on the fender well but i dont know which one is the abs controller.

anyone got a pic of what it looks like? or describe it?

thanks.

 

Do the instructions identify the wire color you are looking for? The ABS controller is under the battery box, and is a PITA to reach.

If you know the wire color needed you might be able to find it inside the cab.

 

ya its a gry/blk wire.

but i found it.
it is just infront of the battery box and lower than it. i moved the wheel liner and got to the wires. and found the one i was looking for.

thanks though.

 

Cool. The gry/blk wire also runs to the instrument cluster....so it is in the cab too if you needed it.

 

that would have been easier but i spliced into it by the abs module. it works great. i now have an accurate speedo.

 

Awesome. How hard is it to dial in the truspeed to get the accurate measurement?

 

talk about bringing one up from the dead.

i didnt see that last post.

i have a gps reciever and used that to get it spot on. the method that they tell you gets you close. (they have you calc a % difference and then adjust the calibrator according to that).

w/ a gps it took me about 3 different adjustments and it was perfect.
