Hello friends, I am new to the group, I need your help, I have a dakota 98 3.9 4x2, which want intalarle one ax-15 transmission, what I'm encountering is in electrical connection, as I can fool the computer, if anyone has a diagram of how to make the connection, I would appreciate greetings from chile

 

Welcome to the forum Dinko.

Are you removing an automatic and putting in the AX-15?

What connections are you having trouble with?

 

Excuse my English, as I donot modify the circuit reached the automatic transmission to turn the truck with AX15 transmission

 

Sorry for my English, as I modify the circuit that reaches the automatic transmission, to turn the transmission AX15

 

The wiring harness is different, auto to manual (AX-15) as is the PCM (the engine computer). On an automatic transmission the PCM controls some functions, like the torque converter lockup. You'll need a new PCM for the AX-15 or will get codes. It should still run though.

The only connection on the AX-15 should be for the backup lamp switch.

You can modify the harness to work with it. If the wire colors didn't change (don't have a manual for a '98), the brown with light green striped wire should be the feed for the backup switch, the violet with black stripe is the output to the backup lights.

The black with white stripe wire is the neutral safety switch. To bypass it just connect it to ground.

 

By modifying the harness is not necessary to change the pcm? And when you connect the 4 ground wires do not need to make another connection?

 

You'll still need to change the PCM. You'll have trouble codes if you don't because it will be looking for inputs from the automatic that you no longer have.

The only connections for the manual are the backup lamp, the two wires. You'll have to ground the neutral safety lead just to bypass it so you can start the truck - that should be it.

 

The manual pcm the first generation 95 96, can be installed in a 98 or has to be the same year?

 

Same year. There are big differences in the PCM's, especially with regards to the on board diagnostics.
