I'm currently doing this swap.
93' b18a1 into a 93' Civic EX
My harness is pluggin up fine to the LS ecu.
My problem is the harness pluggin up to the engine.
On the passenger side I have 3 plugs out of the firewall, Only 1 the biggest one is plugging up.
On the drivers side only 1 of the 3 plugs comming out of the firewall are plugging up. 1 of the 3 plugs has a block plate so its not used.
Do I just leave these un plugged? I really don't see how it would run.
Please help. I went from a d16 to a b18c sir g and now to a b18a1. I didnt have any of these problems in my last swaps.
I bought the cable to hydro conversion, just got it in today. [got it for $35.00 shipped] and am in the process of getting all the motor mounts brackets ect, I sold the mounts that went with my old b18c ;(
Thanks for your time. I really do need the help, this is my only car and it hasn't been running for over 2 years.

 

im pretty sure it wont start if the sensors arent connected. Do you have your stock harness? If so just use that. If not your going to have to find one from a 92-95 civic or 94-95 integra
