is there a difference between the wiring harness for the 88-89 crx si and the 90-91 crx si? i have an 88 crx si, the injector resistor box plugs in fine... but the plug next to it is rectangular coming out of the car, and round off the motor. do i just need a harness from an 88-89 crx si or do i have a bigger problem than i think on my hands?

instead of having the round harness mounted on the chassis i have a small rectangular box for it help me plz.

 

I had the same problem but mine was a 89 Crx and I had gave away my orignal engine harness with my motor . I thought a Da Teg would work (Which it did except the End connector next to the drhich ivers side firewall whappend to be a Circle ) I had a Square connector(Da Harness = square connector). So i ditched the harness and came across a 90 Civic Si Harness which happend to have the circle connector that i needed

 

my advise is get a matching set or wires. i went thrue this crao fro a while with my crx. 88 has some weird wiring and 88-89 is different from 90-90 fo sho. good luck with it tho

 

Yeah I had similar problems with this, the solution is to simply either cut both plugs off and directly wire the two together (match up colors) or you can find any 89-91 crx (MPFI) main car plug (circular plug that comes out from the fire wall) and replace your square plug with the new circular one. there may also be a conversion harness.

 

hey man you remember me? lol you work at autozone right, i found that harness but i musta used it for a dpfi to mpfi conversion. sorry bro if i can help lmk

oh yea im the guy with the crx/h22, look up my user name and u'll find my posts

 

rule one, dont mix and match at all... 88 si is 1 design, and 89-91 si is another... they are close hovever, just remove the blue and blk/yel wires for the fast idle valve on the 89-91 and match up the rest... problem solved

 

ryan is the man!! ;]
