I need some help with a mini me. It's a 99 d16y7 with a 98 y8 head. we got the head on the block it runs fine but having trouble wiring vtec. We don't have the ecu but I've read about something called a "rpm switch." I was wondering if anyone could tell me how to make this work....

The risk on using an RPM switch is that you can fry the VTEC selenoid plus you're not getting the fuel maps that the engine needs when going into VTEC- best bet is to get the ECU for the EX, Im not sure about which wire goes were in the '98 ECU but here is what I got for the '95 Ex, at least you can have and idea and you can search it one the Net...

" on to wiring vtec

you need the plug on the vtec solenoid with the cut wires......there should
be 2 wires from the bottom harness......and 1 wire from the spool top

1st harnes( 2 wire one).....
1 blue wire- oil pressure sensor
1 black wire- ground
extend the black wire and run it straight to a good solid GROUND
blue wire should be extended through the fire wall straight to D6 on the ecu

2nd harness(1 wire one)
1 green w/yellow wire- vtec solenoid
run a wire from the green w/ yellow wire all the way through the fire wall
to A4 of the ecu

now....thats 1 wire going to ground....and 2 wires going to the should be NO......I repeat NO check engine
light......unless you didn't hook up vtec rite............."

Ok, question.
D15B7 Block
D16Z6 Head
D16Z6 Trans
D16Y8 Harness
Yea, does that work? Or is there an easier way to do it electronically?
