Long story short.
Bought 1993 yj 2.5 4 cyl from neighbor who had set engine on fire.
(something about inj. leaking ).
Purchased under hood wiring harness for 1993 yj 2.5, purchased 1992 under dash wiring harness ( people said would work - same as 1993).
I'm not so sure. Wires hook up the same - some diff. colors.
Most all elect. works- wipers, blower, emer. flashers.
Ign. switch when turned works power above, but will not engage starter.
( in fact when ign. switch is turned to engage starter left rear tail lights but then goes out.
I can jump across stater sol. and engine will turn over.
Have followed red lead from batt to ign. switch- good have power to ign. switch. Have power from ign. switch to st. relay. Ign wire from relay to starter is good but not getting power to starter when ign. switch is turned.
Gauges are pegging. I'm guessing a ground problem but can't seem to find whats wrong.
