A little over a year ago I purchased a complete dash and 2 door wiring harness for my 1994 F150 XLT 5.0 5 speed that had keyless entry and power mirrors. The wiring came out of a 1995 F150 XLT automatic with keyless entry, power locks/mirrors/windows. And I didn't realize until today, it also came with the plugs and control module for electronic 4x4. I have no interest in using the electronic 4x4. But the module is there, and it is plugged in. The plug for the 4x4 switch is not plugged in because I don't have one.

Today my buddy and I did the swap - I had thought I had gone over every single connector before I pulled the old one and put the new one in, but lo and behold, there is a different one. It s one of the connectors that runs down the back of the aluminum bracket on the dash, driver's side. I have provided pictures of both connectors below, with tags - pretty sure it is a floor harness plug but I might be wrong:


Plug on my stock 94 harness - the two big bundles in the background are the two big connectors that go thru the firewall.





Different angle of plug on my stock 94 harness - also shows the other connector that is on this section of wiring.






New plug on the 95 keyless harness - this has replaced the plug in the first picture - you can see the connectors for the two plugs from pic 2 in the background


Right now the one plug is disconnected. The truck starts and runs fine, and the power windows and mirrors work flawlessly. But the locks are having problems, specifically the drivers side. When I engage the lock with power, it sounds like it is trying to rapidly actuate the motor, and it will not stop unless I unplug it. We hooked up a spare motor and same problem. We switched out the plugs and same problem. Yes, both ground on both sides of the dash, behind the kick panels, are secured.

Other weird things - we actually ended up getting the keyfob programmed, but for some reason when you open the passenger door it causes the security light to flash. When you close the door it goes away. The driver door does not do this, but both door switches work and activate the dome light properly.

So I need to figure out how to connect that connector, even if it means ripping out the entire floor harness. And I need to know from someone with knowledge of the wiring schematics of this truck what I am dealing with here. The old plug also looks to have less wires than the new plug,,,,so I am confused at the start.

Also, what to do with the electronic 4x4 module - as of now it is plugged in, but since I do not have a switch or any of the stuff needed for the conversion, should I leave it unplugged?

Finally - when I switched out the blinker stock to one that actually works, I accidentally turned on the hazards, but I didn't know because I did not have a flasher for the hazards in - and it would not let me start my truck. Just crank crank crank but no turn over like it wasn't getting fuel. Figure out the hazards were on, turned them off, and it fired right up. Normal?
