TBI -> ZZ4, how to hook up stock tach???
Ok somebody must have done this before...
I used to have a 92 TBI unit that I completely replaced with a ZZ4 engine which has the HEI distributor. The distributor has a B+ terminal and a Tach terminal. The B+ is obvious where to hook up.
But what about the tach terminal? I believe there are 6 total wires connected up to the TBI distributor/coil combo so WHICH WIRE OF THESE GETS HOOKED TO THE ZZ4'S TACH WIRE???
Any help would be great!
Thanks
