Looking for correct grounding on my project.
I shoehorned a 5.7 with it's 545 RFE transmission from a 05 1500 2 wheel drive pickup into a 1934 Chrysler Business Coupe. Yes I'm a street rod guy. I purchased the stand alone DIY Hemi system and the install was easy so far. I sent off my ECM to get cleaned up checked and skim deleted. Now to the subject of grounds.
It has the ground straps from right to left heads which I landed to my frame. I checked out the ground schematic on Google for my hemi and it doesn't really show grounds landed on the frame and fire wall for the ECM, motor, or tranny.
I'm looking for the correct answers on where engine, and tranny grounds need to be landed for the ECM, 5.7 block and 545 RFE tranny in a bare bone street rod. Someone must have done this, race car etc.
Thanks in advance.
You need a ground from battery to engine block, engine to body/frame and battery to body/frame. The way to certify your grounds as good is to use an ohm or multi meter and check how many ohms resistance there is between engine and body, engine and battery. You should have near zero (0) ohms of resistance. Something like 0.4 ohms is typical.
