I've heard that splicing can really make throw the current off. I watched a video of a girl working on her Ram 1500 that had the same problem.
she spliced in all 3 PCM plugs and the exterior relay/fuse box (had a fire) and it ran great!

 

For how long?

I am looking at future troubleshooting here. If you splice in 32 wires, that is 64 potential failure points. If you live in the desert, maybe not an issue, if you get any kind of weather, it will eventually become an issue. In all reality, I think it is actually EASIER to repin the connector, than it is to splice/heat shrink all those wires. Take the connector you need, use the special tool to empty it out, (five minutes, maybe) then swap wires from old to new, one at a time. Repair contacts as necessary.

 

There is a special tool? Where does one acquire this device? After 1.5 hours on the bench I gave up....

 

Yep, it's basically just a little round barrel screwdriver, you stick it in, around the contact (pcm side of connector) push the wire in a bit further, then it just pulls straight out. The tool releases the locking clips on the outside of the metal contact. There is a technique to it, but, once you do a couple, it becomes easy.

 

I have to invest in one of those for sure.
Just the little i did wanted to make me drink lol.

 

Try repinning an OBDI harness for MPFI to an OBDII harness. You'll have nightmares about it for MONTHS.

 

If all else fails a carburetored 408 with a 727 is looking pretty good

 

LOLOL. Yeah, that'd work.

 

To bad you can't carb swap these 4.7s

 

don't use the word "can't", because you can.
