damn grab the old plug of the single cam and cut the de plug off and wire the single plug in thats all.

more detail

Locate the body harness (under dash harness that attached to the ECU) that attached to your old harness. Cut the old connector off (the one that attached to your SOHC harness) and attach your DOHC body harness connector. Just match the colors!
Yellow/Red --Tach
Yellow/Green--Speedometor
Orange--Ignition start
Black---Ground
Blue/Black---Water temp sensor
There will be some wires left over. These are for the SOHC's diagnostic plug, and are unnecessary. Please note: Your car will NOT be able to hook up to a CONSULT tool.
Use a soldering iron to splice the wires together. It makes for a much cleaner job, and a cleaner electrical signal.
You need to swap out your tach if you want one that works. No wiring is involved, but it must be done. Simply pull your gauge cluster and remove the three screws behind the tach. Lift and separate. Replace.

LOL, they copied my how-to (without asking) and made some changes. I was butthurt for awhile but I've stopped giving a shit. Typical stuff, you know?
