Ok guys i had to rewire my dizzy for obd2 harness because there is no obd2 dizzy that will fit my d15b motor....well im following this diagram as shown below and there are 2-3 wires that are not the colors shown on this diagram...can anyone help me out? im putting the obd2 plug(off of a obd2 dizzy) and wiring it to my obd1 dizzy...my tach is not working and my car is missing...i turned it right off because i knew it was in the wiring and did not want to damage my motor...anyone have some info? or a new diagram...thanks=(
