QuestionGot a question: After I replaced my tranny in the F150 I still had a shift tube to replace. It broke a couple months ago and I would put it in gear reaching under the dash and pulling the cable it was connected to. So the other day I got a new tube and rod and lowered the steering column to replace. There was a box tied up under there that was in my way. I thought it was a trailer brake thing. I removed the harnesses and went on to replace the shift tube. After I put everything back together it wouldn’t start. It turned over but no dash activation other than the odometer and a flicker of the speed and alt meters. So I took the box to the dealer and they said it was an old ford alarm control box and that I should just disconnect the batt and it will reset an the truck will function. NOT!!! No bypass button but a thing in the glove box that you remove the cap. So I said to hell with the alarm and followed the wiring it that that harness was connected to. A couple wires went to the selinoid, a couple went to the coil, a couple went to the brakes and one to the speed control and one to the fuse box. I removed it all and set the wires back to their original color code with no alarm hooked. Still same thing, although I do get fire now, as I sprayed some starting fluid and it kicked. But no instrument activation other than described above and no fuel pump activation. I did pull the relays and main-wired them and the pump does work.. but no dash activation. Tell me what you might do…….
This was not factory installed, and the only wires to the door were speakers.
AnswerThere is obviously a mis connection, or
non recognition from the body control module,
to the vehicle's ignition module.
Best way I can think of is to get a code reader
and see what it reports then apply the fix.
So many hours of hit or mis here to bump around blind
on it. Better to get help for this from Ford direct
so there won't be anything undone.
Let me know what they said. Interesting issue.
