I know the main relay has multiple wires that control the fuel pump at different times (i.e. one wire for "start" position, one wire for cranking, etc.)   Which of these wires do I connect the Megasquirt fuel pump wire to?

I just finished putting the dash in a car. I noticed on the back of the heat/ac controls box there are three plugs for wires. However the harness only has two plugs for it.   88 Harness, it is possible that the heating controls are 87. Thanks.

I need a pressure plate 87 5speed with bolts and I need motor mounts with bolts

So my aem gauge is reading differently then megatune. I set the ms to what the aem instructions said per 14.7 air fuel, i was about to start adjusting the ms until megatune matched what the gauge showed but before i did that i wanted to ask here what settings people usd for the aem
