Wires are tan and purple it is not an injector plug or a cold start plug as this is right infront on the intake

I don't think 1990 uses cold start injector, but that looks like the cold start delay switch connector. It's in the right location at the front of the intake and the wire colors are correct. Could somebody possibly have swapped in an older harness?

I should have mentioned it is an 88 Harness I converted to TPI , I run a 89 PROM so I dont have to use the cold start, that solves it then ill just tape it up and leave it be

Those union fitting look a little scary. I hope you carry a fire extinguisher just in case.
