hello ht. i was wondering what engine harness i can use for my b18b1 obd2 ls engine, such as one out of a 4 door or a gsr maybe im not sure but any help would be awesome thanks.

 

The 4 door one would be fine if it is from a 5spd. variant.

The gsr one would work also, but it would contain a bunch more extremities that would be vital to have if you were gonna go VTEC head or GSR or TYPE R swap

 

sweet that helped a bunch thanks man.
