3.0 liter swap wiring help?

[Subarute]

Hey guys, have a bit of a weird one. I have a 1942 Oldsmobile that I'm body swapping onto a wrecked 1996 ranger 2wd 3.0 5 speed. I'm wanting to keep the original fuel injection and five speed. Mechanically, its all ranger, and I'm trying to figure out just how little of the original wiring I need to keep it running on the stock ECU. Ideally I don't want to use any of the ranger gauges, and I'm pretty sure I'll need to use the original key for the truck, as well as the engine harness and ecu but is there anything else I'll need to make the engine operate as stock? How much of the interior harness is required?

Why not use the wiring from the ranger? You will need new wiring anyway correct? There will be a bunch of wires for the fuel injection, why not a few more for the lighting and the original fuse box? That way the original ranger wiring diagram will work also.

You will need the wiring going back for the fuel pump. Might as well run the original rear taillight wiring with it. The fuel injection used a pump on the sending unit. So if you want your fuel gauge to work, you need to use the ranger fuel gauge. With a little head scratching I am sure you could retro fit the newer gauge behind the old dash.

Is the 96 and OBD II ecu? If so, I think the instrument cluster starts getting a bit more complicated and computerized. That's going to be the difficult part. A guy around here put a Bel-Aire dash in his Ranger. He might be the best one to talk to about the gauge cluster.

Aside from that, I, personally, would strip all the 42 wiring out and start over. Put the engine harness and ECU in from the truck and then just wire everything else new. The insulation on that 1942 wiring is old and brittle and will be nothing but trouble. Just go one circuit at a time and wire it the way it needs to be.

I was going to do all the wiring fresh from the 42 anyway, I was just trying to minimize The rat's nest that I would have to deal with

It is in fact an OBD2 truck

No way to avoid the rats nest if you are going to use the fuel injection.

P.S. I just looked, this engine was a newer design that came out around 1986 and never was carbed, so it's fuel injection or nothing.

Best way I know to deal with the rats nest is to start clean and wire everything fresh and dont put in stuff you don't need. The engine harness and ecu is what it is. Can't delete much there except maybe egr.

IDK about a 96, but the earlier trucks had a mostly separate engine harness and body harness anyway. I would expect Ford to have kept that going for cost effectiveness with multiple drivetrains in the same body...

Isn't 1996 the first year of PATS, so you have to keep either the PATS module or the instrument cluster if it is embedded in the cluster.
