Same swap we did in mine. You're going to have to splice alot of wires since the plugs are different. Injectors, etc. You're also going to have to wire for a 2wire iacv. The third wire is just going to an empty pin.

The major thing is that you're going to need to get an obd2 distributor or use the internals from your Dseries (what we did). Because your obd2 has the crank position sensor in the distributor rather than on the crank pulley side of the block like the obd1.

As far as an ecu get a jumper harness and use an obd1 LS ecu (p75 I believe?)

It's been a while since I did it, so I can't remember alot of the details. I just remember alot of soldering.

You can get a harness already done from Hasport if you don't want to splice it yourself, If not you'll need an OB2 dist. like Munster said, also an OB2 alternator, and you can get OB2 injectors insted of splicing your old ones too........................

I did the opposite, my car is OB1 and I put an OB2 B16 with a P28 in it.......GOOD LUCK !!!

You don't have to switch anything if you use the obd2 distributor. You'll just have a sensor going to nowhere hanging on teh side of your block (like mine)
