Check your factory installed Auxiliary Battery


If you have an auxiliary battery installed in the engine compartment, make sure that no battery acid is washing down onto the ECM. I learned the hard way to the tune of $5000 when water got into the multi pin connector between the ECM and engine wiring harness and ate away the pins and socket. Now I have a sealed AGM battery, and I am going to design a cover for the ECM.


Ouch, not good, thanks for the heads up!
