OT: Harness adapter for VAFC?
As far as I know, Kenji makes it for King. There is no such thing as an adapter harness from Mugen, so to speak. You will have to splice into the harness to use the V-AFC, which eliminates the need to splice into the stock harness (which you don't want to cut for warranty reasons btw). The Mugen ECU is OBD1. The harness converts the 2K+ harness to OBD1 equivalent.

IM Kenji Plennert on this board. He makes them. $250 US I think. they are the same ones you get from King Motorsports to run the Mugen ECU.
Here's a gratuitous, bandwidth-intensive pic of the Field Vtec controller harness:

This one, Field part # VT-H6 should fit the 97-98 ITR. But I'm pretty sure that they also sell a model with the '00+ pin-outs too.

Man.. I can't believe how much they can charge for pieces of plastic and wire.
If you had those plastic adapters, wire, and a wiring diagram, i bet you can put one together yourself.

It would be really easy to make since it's just a jumper harness. You wouldn't even need a wiring diagram. It's just hard finding the connectors. The field is cheaper but you need to cut into the wires. Kenji can probably make a totally plug and play one. It's up to you.
Well I heard that all that krimping and wiring takes a lot of time to do, and the ones you buy are already tested for problems.... Saves a lot trouble to buy one.
Does Kenji make one that will plug and play? If so that would be best!

Or you could get a Field harness. They are $50 cheaper.
The Field harness is "plug and play" already. Look at the pics. See all those bullet connectors? That's where you plug in... The RPM, throttle, power, pressure, etc. wires are already color-coded and equiped with nice bullet connectors for you. You don't have to cut anything on the Field harness. You just need to attach bullet connectors to your V-AFC wires to plug 'em in.
I'm not sure what you mean about it not being compatibile with OBD2 cars... It's just a wiring harness. You just need to get the model that has plug connectors and wiring that match your car. The model in that pic (VT-H6) works fine on 97+ OBD2 Preludes and 96-98 OBD2 Integras. You just need to find out if Field makes a model that fits 99+ integra harnesses...

It will not be totally plug and play. the bullet connectors are for the field controller. vafc uses some of the same connectors but requires additional ones such as tps sensor but doesn't use the speed sensor. vafc also requires you to tap off the power twice and the ground twice. so you will have to cut into the field harness a little to make it work with vafc.
> yeah, for 6 bucks worth of wires and overpriced proprietary connectors!
Are the connectors proprietary? Surely they could be bought from a Honda/Acura dealership? The plug that the ECU slots into (whether it be ODB1 or ODBII) should be in Honda's parts catalogue?
To make an adapter oneself, all one would need is an OBDI and OBDII connector from the local parts department, a few dollars worth of wire, a pinout diagram (freely available methinks), and some patience.
Am I missing something?
