caperix Posted August 12, 2013 Share Posted August 12, 2013 The engine going in my Z car does not have a engine wiring harness. I am having trouble finding a good one at a salvage yard, most I find are over price & of questionable quality as they are 20 years old. The painless harnesses for the TPI motor are very reasonably priced & I am leaning towards using one for the engine. Has anyone used one of these, I know the JTR book recomends using only the GM harness, I have not tried to source a new one at my local dealer yet, may not even be available. My only issue with the painless harness is that they are set up for a 700r4. Is it easy to change them over to a manaul transmission?

rsicard Posted August 13, 2013 Share Posted August 13, 2013 If the painless harness does not require an input from electronic speedo generator, then just bag and tie back any wiring for the 700R4. The ECM/PCM could care less. Quote Link to comment Share on other sites More sharing options...
