opinions needed regarding available EFI for a small block
I could take some for you if you really want, but it just looks the same as popping the hood on any 90's dodge truck. What pictures would you want specifically?
ECM Mounted on pass fender:
Three relays needed to make it all work:
OBD1 setup ECM mounted on drivers fender (used a van harness) + TTs
As far as a parts list, I used the stock harness, ECM, sensors and either 2 or 3 relays depending on OD or nonOD trans.
Found a wiring schematic relevant to the year engine, ECM, and harness I had.
I then Identified the leads needed to power the ECM, both constant power and keyed-on power.
I nipped the bulk connector at the end of the harness opposite the ECM.(normally goes to the relay bank)
I put constant and keyed-on hot to the ECM via the correct wires.
After that I considered what else was needed for the motor to run. With the hots hooked up that provided me with Spark, and air is a given. So I needed FUEL. The design theory runs the fuel pump relay through the ASD(automatic shut down) relay. So back to the wiring schematic, to determine how the relays get power and signal from the ECM. Once these two relays are hooked up the engine with run and do everything it's supposed to. It will generate C.E.L.s for things such as EGR, pre/post cat O2 sensors, or other items dependent upon standard equipment for that engine. But non of these codes have ever put my car into "limp" mode.
