yes like cobber said a multimete ris yr best friend
yr best of buyign a book to learn how it all works
blinkers are piss easy but headlights are fiddly
not hard just u need to understand hwo they work
especially if u want the pass high beam feature

the colt and sigma and ford laser all have their own minute differences

but a mutlimeter on buzz will help alot

after yr finished the body wiring u will understand why painless wiring looms are not so painless heheheheheh
