Rbenys14 Posted August 11, 2017 Share Posted August 11, 2017 I've been putting in alot of time in the garage trying to tuck and shave my bay along with installing megasquirt. My only question about the whole thing is, how am I to ground the million black wires? I've read NOT to ground them all in the same spot. I've also read NOT to solder them into a bigger wire and put it in a single location. But I HAVE heard that I should ground everything to my block. I'm currently wiring the injectors. Where do I ground this bundle of 6 black wires? Tha k you very much for your response. Sorry if this is in the wrong place or already posted. Still trying to figure out forums.

softopz Posted August 12, 2017 Share Posted August 12, 2017 I put them on a thicker gauge spade crimp and solder them, than ground on head/block/battery > If your doing on the head or block its good to have 2-3 grounding points from battery Quote Link to comment Share on other sites More sharing options...
grannyknot Posted August 12, 2017 Share Posted August 12, 2017 This is your bible, http://www.megamanual.com/mtabcon.htm Can you post links to where it recommends not to ground to the same spot? My rule of thumb was if a wire has anything to do with MS then ground it to the same spot, the system is running perfectly. Quote Link to comment Share on other sites More sharing options...
Derek Posted August 12, 2017 Share Posted August 12, 2017 Shielded wire and single point grounding will be your friend. Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted August 14, 2017 Share Posted August 14, 2017 Split mine up into 2 separate spade connectors. I believe 3 in each connector. Then both spades grounded to one of the starter bolts.I find their literature hard to understand. Your not alone. Quote Link to comment Share on other sites More sharing options...
Chickenman Posted August 14, 2017 Share Posted August 14, 2017 I prefer grounding to the head or block far away from starter or coils ( If COP or CNP ) . Starter is a high EMI transmitter. I don't like any grounds near it. I've also read that you can get eddy currents near the starter ground when cranking. Those can induce impedance in the ground wires.
