i have a 91 civic with a d15b2 that i swaped a sohc obd0 zc into. i bought a obdo si harness and the large connector on the driver side does no fit and there is an extra connector on the passenger side by the fuse box. what do i have to do to modify the connector by the driver side, and what is the spair connector. im so close to this swap being done yet far. has anyone done this swap with this set up,what did you do??????

 

it sounds like a dpfi to mpfi swap.

did you maintain the b2 intake?


there are plenty of write ups of this swap.

i will post up pics of the crx that i have sitting to identify Mpfi harness plugs.

I do believe they are plug and play as long as you have a manual. it seems you may have an automatic harness.

 

the guy i bought it from said that it was from a 5 speed. everything matches and fits except the end connector on the driver side, and the extra connector. the zc that i bought has the multi point mani on it and the si harness matches the injectors distributer ect... the connector on the dx chassis has more wires than the si harness so i cant just swap over the old b2 connector.

 

Dude you can't just expect to plug it in and work with your DX cabin harness. You use the si harness for certain plugs and then you add wires to your existing DX harness (injectors/ dizzy). Search for DPFI to MPFI write-ups.
