s4 n/a ecu ground pins?
 

wich pins on the ecu of an s4 n/a are grounds? thats all i need to know. thanks

check out www.1300cc.com in the safc install he has the ground labeled. it should be black. i think its one wire splitting into 3. im not %100 sure that theres only one ground though.

i just found an original rx7 technicians manual. the ground pins are as follows... 2C, 2R, 3A, 3G, and 3I... the linked helped out too thanks

Sorry, but I think you'll find that if you ground 3I you'll blow a fuse. Ain't a ground the last time I looked.
