Re: TPI WIRING HARNESS

Having never done that exact swap I can't say for sure. Certainly an auto trans car setup is going to have one more hookup that you won't have with a manual- the torque converter lockup.

I suspect that the T5 with a cable (assuming that's what you mean) isn't going to work with an ECM designed to work with a trans (any trans) that's designed to have a direct link to a VSS in the tailshaft, but I would wait to see what othrs have to say on the subject.

If a T700 VSS won't fit in the T5 you need one of these ( depends on what year ECM you are using; different signals ) to give the correct VSS signal to the computer .
Just connect to the purple and yellow wires on the TPI harness that went to the auto VSS

The 4 pin plug on the TPI harness that went to auto for convertor lockup you don't use on a manual

Re: TPI WIRING HARNESS

I've used the speed sensor/gear drive type sensor for 90-92 Camaro/Caprice patrol car in at least half dozen TPI streetrod type installations. It has the VSS plug to go to ECM and also used a cabel drive for older speedos. Works great.
The 67 Firebird vert in sig is using that setup.
I can get you a Delco part number when I get home if you need it.
Standard, I believe makes the same part as the Delco unit.

Re: TPI WIRING HARNESS

the cars speed sensor is a manual cable dont have the vss sensor on the tail shaft the only connector in the t5 is the reverse and shift light i dont need the shift light all i need is the reverse light thats why i thought is i used the auto harness i would only use the reverse light connector and nothing else looks like it would work but i wanted to make sure before i yank it all out
