Does anyone know what is on the other end of this ground wire, i.e. what circuit ground returns are connected to this "harness ground?" I cannot find any schematics of the RX-7 wire harnesses, and the illustration in the manual is too vague to determine which ground point it is. Have looked at page Z-28 (wiring diagrams), section "Y - Ground Points" but cannot see which designator might be the one in the picture.

 

I think it goes to the battery it is part of the starter harness.

 

Yeah, it's part of the starting/charging harness. It has a tab in the middle of it that bolts to the bracket on the driver's side shock tower and it finishes up at the negative battery terminal.

I've rebuilt my starting/charging harness out of multiple harnesses so I know this one well .

Its just the main engine ground. Thats the most important one.

 

Thanks! No wonder I couldn't find it... that harness isn't even listed in Section "Y".
