Start simple. Double check to make sure the solenoid and started are hooked up properly. Fuses? Relays?

After that...it's making sure that the pins at the cannon plug are in the right spot. Unless you swapped in the dash from the 4L truck too.

wait could you explain that more i kept the stock dash in

Double check where you spliced your wires. Make you you swapped them correctly.

i didnt splice anything i just plugged new harness in

Thats your plroblem. No 4.0 swap is 100% plug and play (that I know of). Pickup a wiring diagram for both your truck and your donor. All your splicing should be in the 2 plugs on the drivers fender well (one grey one black).

Or you could just swap the rest of the harness.

would that cause my truck not to start?

 

[Deamers87ford]

how would i splice the wires?

That big white plug on the firewall....the round one. One truck being 2.9 and the other 4.0....some of the pins in the connectors may be in different places, and may need to be switched around or just cut and spliced directly together.

Might need to get ahold of this guy. Rickcdewitt or even AllanD.

well i cant get this figured out so i guess i got some parts for sale now

Dude its not that hard. You've done 95% of the work already.

 

[Deamers87ford]

How do I figure out what wires I splice

 

[disciplerocks]

You need both wiring diagrams.

Here is a helpful link too. Its for an Explorer harness, but it explains which wires are needed to start it.

I Cant believe you swapped a 4.0L in place of a 2.9L, went through all that work, and now your giving up because you wont look at a freaking diagram.

You officially suck.
