DO NOT, I REPEAT, DO NOT
by an aftermarket controller.
I was/am helping another member who also needs a controller. (Power Module for an 87 GLHS)
He originally bought a remanufactured controller (Cardone) from Rock Auto for whatever problem he was having and thought the controller was his issue.
After installing the aftermarket controller he encountered other issues and then I posted diagnostics for the issue he was having.
After posting diagnostics for him they led to replace engine controller.
He contacted Rock Auto, returned the defective controller and they sent him another controller which was in worse shape than the first one.
I told him that when I first saw his post about installing an aftermarket controller that it made me Cringe.
I also told him that Autozone kicked Cardone to the curb because of quality issues with ALL
of their products, especially Engine Controllers.
When I was the Commercial Sales Manager at AZ (2012- 2018) we sometimes had to order 3-4 controllers before we got one that was good, you can imagine how pissed off the commercial accounts (shops) were with this and obviously their customers also.
The Original Mopar Part # for your controller is 4778002, that part # has been superseded a few times.
Supersession(s): 04714254; 04686284; 04741018; 04778002; 04639472; 04723525; 04672128
My recommendation is to find a Used/NOS/Working Mopar SBEC.
1)Found These Online
The "R" in front of the part # indicates "Rebuilt by Mopar" and these units were sold at dealerships, they have since been discontinued by Chrysler.
I have dealt with RPN (the seller on RearCounter.com) in the past.
I purchased a Mopar Clutch Cable from them, they were friendly, not expensive and the part arrived quickly, I would use them again.
