If this is a bigger motor too you need to consider changing the
resitor strip that gives you speeds because the stock one may fail in
time under the heavier current draw from a bigger motor.

Re: CJ-5 Heater Fan Upgrade Questions
I just clicked on something.... You have the backfire issue in the
other group right?
The orange wire from the choke sometimes hits the exhaust manifold near
the back which will cause that. The Ford coil connectors are pretty
crappy and either could have been moved or dinged when you were in there
trying to bolt the heater back on. Even a plug wire.
I also have posted a meter walk through for you to test your connections
so you don't have to tear everything open on your alternator harness.

Re: CJ-5 Heater Fan Upgrade Questions
I just clicked on something.... You have the backfire issue in the
other group right?
The orange wire from the choke sometimes hits the exhaust manifold near
the back which will cause that. The Ford coil connectors are pretty
crappy and either could have been moved or dinged when you were in there
trying to bolt the heater back on. Even a plug wire.
I also have posted a meter walk through for you to test your connections
so you don't have to tear everything open on your alternator harness.

The are both stock GM items. AMC used a GM heater setup with the same
resistor pack which is why the larger motor fits right in and to the
