The cable drops down from the back of the plenum. There is a clamp holding a wire loom that's connected by a bolt. You can attach the cable either under that bolt or any other point that is metal on metal...just make sure it's not touching moving parts.

perfect, thanks man. Do you happen to know where to attach the TCU and ECU points also?

[Beancooker]

They attach to the TCU and Tthe ECU which are on under the kick plate in the passenger foot area. The TCU is buried up, way up the kick plate. Like almost next to the dash, but in the wall of the car.

***EDIT***

Attach to the mounting bolt on the TCU/ECU.

Explaining by the pics you have in the other thread, in the 1st picture, the bolt that has the arrow pointing at it, that's where you connect the ECU wire coming down and one end of the TCU wire. There's an alternate point with the bolt that's somewhat hidden from view at the top of that picture. The TCU wire goes underneath the bolt that holds the TCU to the chassis in the last picture. The alternate point is the bolt on the far right in the foreground of the 3rd picture.

Perfect, thanks man. Also, I took the battery cover off but couldn't see where to feed the wire down. Do I need to take the battery out to find the boot in the firewall?

[smockers83]

Nope, that rubber dome thing you see in the left corner, make a slit in that and feed it through...use a little saliva for lube. It might take you a few tries but it'll work its way down in there.

These are where I grounded mine. Any connecting bolts should be fine.

As for the transmission, did you feed the wire directly down behind the plenum from that bolt in the diagram? You should see a bolt that holds wires to the transmission. That is what you are looking for, although any place you can connect it to the transmission will work equally well.

Got it! Haven't had a lot of time to drive and test it out but everything is on. Thanks everyone for the help! I know I say it too much but... This forum kicks @$$.

[tollboothwilley]

reset the ECU as well...should optimize it all.
