Converting 89 F-body TPI MAF harness to MS2 harness
I posted this on the MegaSquirt forum but figure I also try my luck here. If things work out, I'd do a write up and get others to be a MegaSquirt'n.

Noobie here. I'm trying to keep as much of the OEM hardware as possible (less the MAF, of course). So far, I've brought over the CTS, TPS, O2, 4 wire IAC, and injectors. This leaves the distributor (pinouts 7&24), IAT (pinout 20), FIdle solenoid (30), IGN/coil control (36) and the fuel pump relay (37). Is there anything else I can carry over or should I just leave the rest as unterminated wiring? I am doing this without the relay board.

minor update
Looks like I'll be using a 7 pin large cap HEI instead of the 8 pin one with external coil (I can't find where the harness that connects the 2 are
), (pinouts 7&24). I realized that IAT (pinout 20) is the same as MAT. . FIdle solenoid (30) is unnecessary when using the stepper IAC. The IGN/coil control (36) and the fuel pump relay (37) looks like the only 2 wires to be left unterminated until I figure out what connectors I need. It sure does help going through the MegaManual a few times. I'm just waiting for the MS2 components to come in...
Shagwell, got a pic of the MAP sensor connector, by chance?
