has anyone ever used a painless wiring harness for a TPI car? what are your oponions on them? did it come with instructoins? was the installation easy?
thanks

 

It blows goats. Installation sux. Painless is NOT for factory replacement, like you intend. I have personally used them to retrofit my LG4 to TPI, and if I had to do it again, Painless would be the LAST option.

Granted, it is an EXCELLENT harness, IF its a "Hot Rod" or other "custom" application. But if you are converting your Carbed or TBI F-body to TPI, its a "stock" conversion, and YOU WILL BE SORRY!!!!!!!!

I'm upgrading my 1980 to TPI. I was considering going with painless, only beacause the wiring harness i have now doesn't mark the injectors!! If not painless, what harness should I go with? Painless is pretty expensive, too

Doesnt matter what injectors you hook up where. Take your best guess.

As for Painless, they misnamed their product, it should have been Painful Wiring.

I heard they are pretty good and will work with you if you have diffrent mods like trans.
Hope it helps.

 

That's right, because TPI is a batch fire system, meaning all the injectors on one bank fire at the same time.
