HKS turbo timer.

Just bought a really old school HKS timer off ebay, and a z31 wiring harness for it too. I haven't got the stuff yet though.

My questions are: What purpose does the harness serve? Does it just make it plug and play? I know there are online instruction manuals online but they are for later model timers. Does anyone have experience wiring up timers? Maybe you can toss a helpful word my way.

To be honest, I'm not even sure what model this turbo timer is. Maybe you know?

Yeah, whenever I install a new strereo I always buy the harness. It just makes things easier. I'd suggest finding out the model number and go to the site to see if you can find a manual for it, if you don't have one.

I got it for $40 shipped. I bought the harness separately for $25 shipped.

When it comes in the mail, I'll look for the serial number and then give HKS a call.

So I got this thing in the mail today. 4 days via air mail from Japan... not too bad. I didn't get my harness though, so I figured I'd try to wire it up myself.

This thing is stupid easy to wire up. All 3 prong turbo timers are basically the same I found out. At least HKS and Apexi are... from what I read.

You have to dig a little to find the wiring for the ignition. Just un-plug the connector and pull it out to get some slack.

3 main wires
Red wire = 12v constant---red with red stripe in car
Blue wire = 12v accessory---blue wire in car (not 100%, I forgot. lol)
Green wire = 12v ignition---black with white stripe in car

2 individual wires
Gray wire = parking brake wire
Black wire= ground

Splice that **** into the ignition wire harness, and you're golden. I had about 45 min into wiring the thing up and mounting it. And figuring out what wires are what in the car with a test light. Best invention evar.

I would have taken pics had I known I would do a write up on this later lol. I may take everything apart and click some shutters for you guys later, but I kinda doubt it haha.
So there ya go, now you can save $20 on a special harness when you go to install your turbo timer.

EDIT: pic!
