is the 88-89 crx si engine wire harness exactly the same as the 90-91 harness? are the pinouts the same? just a quick yes or no answer will do.

got a chassis harness from a 90 crx si and looking for the engine harness also. if anyone has one for sale, my offer is 75 dollars. thanks

 

they the same

 

89-91 Si engine harnesses are all the same - the 88 is different - 88 has no connector for the Fast Idle Control Valve and consequently the connector at the firewall on the driver's side is a rectangular 6-wire connector where the 89-91 has a round 8-wire connector at that location - this is 88 Si driver's side connector:

 

^ yup

 

awesome, greatly appriciated this input. also the picture is perfect and can use this for refrence when someone trying to pull a fast one on me.. thanks again

 

i got a couple 89-91 si engine harnesses but i gota find them.
