    well today i started putting in my new harness and i decided that i am going to mount the ecm under the seat. The harness is the perfect length to go from the firewall to under the seat in one straight line.

    So I am looking for a spacer that way i can put the cover on my ecm with my zif installed. A while back someone posted in a thread saying they made some spacers. I cant find where that was said. I am looking for whoever made them. I am interested in purchasing one.

    Update: I have been working on the efi install for the past 5 days. I have been making good progress. Most of the connections are made. What's left is power to the harness, power to fuel pump, o2 sensor, map sensor relocation, and vss hookup. So far all of the wiring is zip tied and covered in that corrugated plastic sheath. I am making up new ground wires for the body and frame and motor. Also all of the harness wires are at minimum 5 inches from any spark plug wires except for the wires that plug into the distributor but those wires still don't come close to any plug wires. .

    Not everything is hooked up but i did a test start. It ran decent considering the map sensor was not hooked up. I still need to buy a longer vacuum line because i relocated the map to the firewall. I added brand new grounds from the battery to engine, battery to frame, engine to frame, frame to body, and engine to body, and battery to body. Maybe a little overkill but whatever. One thing that confuses me is where the ecm gets a signal that i am cranking the vehicle. The old harness had a wire that attached to the starter but the new harness does not. Where else could the signal be coming from that i am starting the vehicle?
