Hey guys so i just layed in the 4.0 and hooked everything up that i could. Im swapping in the 4.0 from a 1992 Ford Ranger into a 1987 Ford Ranger that had a 2.9 with manual trans in its place. I have kept the 1987 Ford Ranger dash. Now i have power to the dash, i have lights that work and turn signals that work. horn works and everything, i also kept the 87 Ranger Headlight harness. I spliced the Red/Lt Blu wire from the 2.9 to the Pink wire from the 4.0, which im told is for the starter. This splicing was on the drivers firewall. I also spliced a Red/Lt-Grn wire from the 2.9 to the Red/Lt-Grn wire in the 4.0 which i was told powers everything in the 4.0. Now when i ran the ECM into the cab and connected it, i noticed my inertia switch connector for the 4.0 didnt connect into the inertia switch on the 2.9. my inertia switch on the 2.9 has a Pink/Blk wire and a Orange/Lt Blu wire going into the switch, and the switch on the 4.0 has a Pink/Blk wire and a Dark Green/Yellow wire. I spliced the Pink/Blk wire with the Pink/Blk wire off the 4.0, and spliced the Dark Green/Yellow wire with the Orange/Lt Blu wire so i could keep my original switch. Now when i turn the key, the fuel pump doesnt turn on, the relay clicks but the pump has no power. Im thinking something to do with the inertia switch but im not sure. Those wires i spliced are the only wires i was told i need to make the engine run and charge. So im confused. NOBODY will give me a straight anwser to the wiring, i need the wires from the 4.0 harness to the 2.9 harness that power the fuel pump, starter and main power. I can deal with everything else, but i cannot find for the life of me the wiring colors to get the power i need for it to run. I have diagrams and everything, but there is something i am missing or overlooking. PLEASE HELP! I NEED MY TRUCK RUNNING BY TOMORROW! PLEASE IM DESPERATE! THANK YOU!
