This is going to stretch the memory of us old timers 😀
I had my 89 wiring harnessed dieted by Rob Weatherbie back in the day. I’ve been struggling with ECU’s and have decided to put in a Megasquirt based PiMPxs system. It requires the ACT (air charge temp) sensor. Since my wiring harness does not have a connection I’m wondering if that was something that was removed as part of the diet? Does anyone know and/or where the original wire might be in the dieted harness? I’m hoping it wasn’t cut at the ECU connector since it’s behind my dash 😩
Thanks!

The ACT circuit runs throught the Salt/Pepper connections. The white one has that circuit at Pin7, and should be a Lt-Grn/Pnk wire if still there, and goes to Pin25 at the ECU. The other wire to the ACT is a Blk-Wht signal return wire and can be spliced to any other signal return you have on other sensors, located in the white connector at Pin1 and Pin46 at the ECU. Hopefully, Rob didn't remove the entire signal wire.
