My 1st EFI swap was the 90 Dakota stuff in my 48 Plymouth coupe. That has worked out pretty well. I used everything from the Dakota. A 92 is a bit more complex then the 90 was, the 92 is OBD2 while the 90 was OBD1. I believe as long as you are using the Dakota stuff it will still work out well, its when you start swapping other stuff in that causes the problems.


My current build is 39 Dodge truck sheet metal on a Dakota Chassis. I'm using a 91 Dakota donor, which is also OBD2. One of my issues is the donor was a V6 5 speed, and the drive train is a 5.9 auto from a 97 truck, so the V6 stick computer won't work. The 97 uses a digital speedometer and came with a Hot Wire harness. The 91 Dakota dash doesn't have a digital speedometer, and the remaining instrument cluster is incompatible with the 97 requirements. The Hot Wire harness is a stand alone unit unit requiring only a few wire connections to the truck harness. I really didn't want to use the Dakota dash anyway....

On top of that, I can't use the Dakota heater system (its too wide and doesn't conform to the firewall), and the steering column is too long and without a tilt I need for my 39 truck cab, so I'm using a different steering column and the wiring doesn't match up. It doesn't help that I don't have a wiring diagram for a 91 Dakota, there has been too many wiring changes from the 87 Dakota FSM I have. I thought I could clean up the under dash wiring harness, but there is this under dash control module causing a problem or 2. If I wasn't cheap (and broke) I'd just buy a $250 wiring kit and be done with the whole mess. I'm having fun now!

It is unfortunate that winter has come and the truck is sitting outside, too far away to be pushed in or out of the garage, and too far away to reach with my electric or air, and I'm a wimp, so its cold out there. Come on spring!

Keep moving forward, its nice to see guys making progress. Gene
