B16A swap help

[vtecmatt]

Hello,

I just swaped in a B16A engine into my 99 Civic and when i was about to hook up the ecu i ran into a problem, the wire harness from the engine has 3 connectors but there is another one left over from the D16 that was in there before.

The forth connector is (the extra one) has the following wires:

My question is.. is there an adapter i can buy or a guide on that wire to cut and splice in?

If there's any information I left out that you may need to help let me know!

Thanks

Did u get the right jumper harness? Is it for obd2b? Cuz if not u might run into that problem

 

[vtecmatt]

the one that i have is OBD2A not B from what I've seen online the OBD2B harness only takes in 3 connectors unless I'm mistaken

My 99 civic ex has two plugs on the engine harness and one plug from the cabin harness all three plug into the ecu.

I'm using the wire harness that was on the b16 that i pulled from a 97 civic not the one from my d16

97 was OBD2A. Might be your problem. (EDITED)

If i look up the pin outs of an obd2b to obd2a conversion harness and just splice the wires in from the other connector would that work? If not should i use my d16y8 harness and if i do what kind of modifications will i have to do to the harness?

Thanks

96-98 = obd2a
99-00 = obd2b

^^^^ Correct....I cannot believe I said 97 was OBD2B.....its OBD2A. Edited my post

I'd just put your car's original harness on the b16.
