Hi so a friend had the wire harness coming out of the ecu poorly placed next to the exhaust and the wires are all melted
does anyone know if both sets of brown red and black wires are spliced together for the can signal or is the can signal the three wires closest to the grommet

also on the side away from the grommet the two yellow wires does any one know what they are for one should be coolant temp I think and one should be tach I think any help would be greatly appreciated as I try to help him re wire it.

 

Did you; or your friend, contact the manufacturer to see if they would sell him another wiring harness? Or at least give him a wiring diagram.

I'm surprised it didn't come with a wiring diagram. I'm pretty sure anyone can go to the Summit Racing or Jegs website and download the install instructions and wiring diagram for a Holley Sniper. 🤔

 

I checked my MSD book, but it only covers ignition. Summit has the destruction manual for download.
