Despite my successful cold start this morning, I will get a spare control module. Comparing diff ones. I want a black case as I believe it should have been originally. Other than that doesn.t matter too much. Biggest functional diff is some are supposed to be better at high rpm . Not really an issue for me.
Looks like 4 vs 5 pin not a secret anymore. Hardly any 5 pins available. Guess most are only making 4's since they work for either.
This is from Spectra:
4 Pin module The replacement module you have purchased is equipped with 4 pins. Chrysler production modules now have 4 pins compared to the 5 pin original module and is the current application design for your vehicle.
Similar info from BWD:
5-pin vs. 4-pin: All Replacement modules for Chrysler applications have 4-pin connectors. Early O.E. modules had 5 pins while current Chrysler production also has 4 pins. THe New 4pin modules are correct replacements for both O.E. types (except Dodge Trucks with heavy duty emissions cycle carburetor with electronically controlled vacuum kicker).
I did look and the one on it is 5 pin. Not sure, but I think it's from AZ and as far as I can tell their Duralast is actually the Airtex module-which I think someone recommended against... Probably get the BWD that shows in stock at my local Pep Boys for $20.
