Hello everyone,
I really need a TPI harness and matching computer for my 93 LT1 350...any leads would be helpful

 

have a complete tpi system with computer and harness but they are for an 88 dont know if they will work

 

I have a 1992 speed density ecm and wiring harness. No memcal though.

 

Maybe I missed something, but why would you want a TPI control system on your LT1?

 

because I am running a Computer controlled distributor, and a factory water pump from a TBI setup....plus, Most LT1's didnt power the 700r4...the TPI's did...much eaiser swap ya know?? 700r4 is on roids, so Id rather not remove it..only 150 miles on it...

 

hey, you lost me on the "memcal" if its something I need, what would you want for it....been out a car since this time last year...blew my cam...5.0 just isn't worth fixing up ya know?

 

Im curious how you got the SBC water pump onto the LT1, and why it would matter for harness choice

Never the matter, 92-93 LT1s had the 4L60 behind them so shoot for one of those harnesses for a direct fit, or use a 94-97 harness with a vacuum lockup switch
