wiring auxiliary lights

just curious, whats the idea behind relays when installing extra lights? i have 2 150 watt KC's on my 78, but i dont have them wired with a relay. im just wondering how it works and why you use it. thanks

a relay helps so you dont have to have such a high amperage wire running though your cab.. you can power the switch off something like your cig lighter then run that wire up to the relay. it also helps that you can mount the relay somewhere that it wont get wet and prevent a short like your tail lights.. lol

thanks for the expalnation. like im the only one here thats ever tried to float his truck...... riiiiigght. i guess it wouldnt be a bad idea to go buy a relay and hook them up the right way then. but riht now i got bigger problems with it, story of my life....

dont we all.. lol.. i had a nice surprise from the 85 a few weeks ago.. pics just dont do it justice.. lmao.. all this from a sparkplug that blew apart..

dangit man, im hopin all i gotta do is change out a fuel pump, but you got screwed on that one. my fuel pumo will hafta wait tho, theres a couple other things comin that require my money first lol

you should be able to pick up an electric pump for 20 bucks at autozone.. they are cheap and get you by for a year or so.. all you gotta do is pull off the lines from your stock mechanical pump and plumb the eletric one in.. use the stock pump as a block off plate but pull out the rod that goes into the timing cover..

ehhh, id rather jus put another mech pump on and be done with it. the one thats on there only has abt 2k on it. it ticks me off.
