i got 93 civic cx, w/ b16 swap

the msd digital 6a has a 2 step rev limiter, and im installing it threw the cruise control swtich on the clutch

i did not know the cx came with this switch, so i went to the junkyard and grabbed one from there

when it came to install it, the switch is already there, so all i did was unplug the one in the car, wired in the harness i got from the wreckers, and left the one in the car unplugged

i dotn have the motor in the car so i dotn know what is going to happen

i know there 2 swtiches on the clutch, the other one is for the starter adn stuff and this one is for crusie control, well the ecu throw a code? p28, and will it affect anything else on the car?

i dotn wanna drop the motor in and find out that this is gonna scrwe anythign up

thanks
