"I was wondering if it would be okay to mix a positive wire with the black wire for light-up purposes? (This is in regards of the tq lock-up switch) Because thats the only way I can get power to light it up. I have a three pronge SPFT illuminated switch. It goes "POWER, AC, GROUND." I spliced the black wire already to the Power and AC but was wondering if I could also tap a positive wire to the power also and just ground it for illumination. Thanks."
ok...this is a bit confusing, so im going to simplify:
you are hooking up a switch and wonder how to make it illuminate. is that right?
each prong has a purpose, maybe this will clear it up for you:
POWER: a main power source. could be a constant form the battery, a source that only comes on w/ the igntion, etc. it is where the power will be DRAWN from.
AC: this will be the "output" of the POWER part. when the switch is in the "on" position, a physical connection will be made between the AC and POWER prongs, letting current flow through.
*side note* you can only hook up these two prongs and the switch will be functional. each "end" of the system (the cars main electrical system, where the POWER is connected, and the device you are turning on/off) have thier own grounds, you are already completing the circuit by connecting the positive energy transfer between the two.
GROUND: this is only there in order for the light in the switch to work. as you turn the switch on, the light inside the switch "taps into" the positive power connections, but needs a ground in order to complete the circuit. this wire should be connected to an appropriate ground connection somewhere near the switch. assuming its somewhere near the dash, tapping into the negative wire on the cig. lighter is a great option.
edit: left something out, lol. never touch a ground wire to a positive wire that is hot (e.g., capible of completing a circuit). im not sure what you mean by "black wire", but i assume you mean a ground wire. if you do that, you will just blow a fuse, or cause the wire to melt and risk fire.
:shhh: i do cocaine :/shhh:
