run the vtec solonoid to msd switch's positive output. hook up the positive and negative to ur battery then u should have tach wire to hook up. u hook the tach wire to the tach wire on ur ecu harness. i would get an oil pressure gauge tho so ur not hittin vtec with no oil. good way to blow ur engine.

racingant

are u shore that how to run it i was told that is wrong

JDMorgan

yea. its a 1 wire vtec setup. i wouldnt do it but thats the only way to really do it using an msd rpm switch. what did ya hear?

racingant

its 89 honda civic with an 93 single v-tech can u tell me where all the wires go please thanks for the help

JDMorgan

you can hook the white wire to negative side of the coil, yellow wire goes to vtec, black wire you ground out anywhere on your body and the red wire you can hook to a switched positive, or right to the battery. it shouldnt hurt it to keep it on all the time however it wouldnt be pretty easy to hook it up behind your radio, and hook the ignition wire on the radio to the red wire on the rpm activated switch.
quick chart if u dont wanna read my post
Red - ignition wire on back of radio
Black - ground
White - negative side of your coil, you have to pull ur cap off the distributer to check which color wire it is coming out of the dizzy.
Yellow - run to vtec solonoid
Grey - not used

i was told that i have to us a relay is that true but i'm going to try it your way also thanks let me know about relay ight

JDMorgan

no, the msd switch has a relay in it. it says how many amps it is capable of in the instructions i forget how many tho. you def dont need a relay tho.
