i just got done putting my obdo b18 into my 91 hatch i used the 89 crx si harness that was used with this swap before but i have no tail lights reverse lights or fuel pump there is no power going to the fuel pump at all . . . the main relay is fine all grounds and fuses are good it cranks but still no fuel is there any one who can help me figure this out???

 

dam i got the same problem but i just ran my fuel pump 2 a switch but still dont got reverse or brake lighting

 

i figured my problem out my whole harness is crx except the fuel pump part . . . and thats different from the crx so either if you have the one from the crx that goes back to your brakes and fuel pump use that it will make things alot easier . . . if not you'll need a plug like the main one in the front of the fuse box that goes to the dash harness and right beside the main relay there is a plug that is supposed to go to the fuel pump harness just pull all the pins out of the plug and look at the harness to the fuel pump look at the colors and match them up using the other plug that fits that one and you'll have power back there if you have any more questions pm me
