Ok I have a Msd activated switch that and I am trying to use it on my d16y8, I got a swap but i did not get the harness from the donar car, so i am trying to activate VTEC with MSD RPM switch. Is it possible? Anyone hooked up this setup up before? I am technologically inclined but i just would need to know to hook what wire where.

If it is possible to use the switch?

If you would like a link to the switch I have,

I also bought the 5k to 5.8k modules.

 

Its possible. its a simple 12 volt switch that is motivated by rpm.

wiring, well you'll have to figure that out.

 

Can any one tell me what wire needs to go where for this application?

 

you will have to wire in a relay and change the polarity of the switch from - to + i have wired up a few of these on a few mini me engines. what year is your car?

 

ok the msd rpm switch is a negative trigger, so i dont think i need to use a relay. I have pics below of the two connectors. I just need to know which wire do i connect the switch to on the solenoid to activate the vtec? And Then i need to know what to do with the other two wires that will not are not hooked to anything.

 

pic and where they sit on the engine

 

What ECU are you using, and what year is your car?

 

hey dude i saw your thread and i have the same problem as the other guy. i am getting a p28 and the right harness looking to wire it up for extra money on the side?.....or can you rig a 1.6 91' hb ecu for vtec i have the d16y8.
