my personal vehicle is a 1990 c1500 it use to be a dept of transportation vehicle so its factory yellow. we put a cowl induction hood on painted black strips on and under the hood i have a carb 350 with a rpm intake, cammed, roller rockers, a 2800 stall coverter, hooker headers, and real true dual flowmaster 40 2.5" exhaust no cats. i have beatin a 99 silverado, a 07 avalanche, and a 07 silverado. now for the question i have a cheyenne grille so its one big sealed beam and i have a black 454ss grille i know the black wire is the ground but is the green wire the lo/hi beam or the brown wire lo/hi im wonderin which is which i cant find anyone that has done this kind of grille swap, and im planning on getting a 454 and making it a yellow 454ss clone

 

soo could anybody give me a little info on doing this because its like i said the green and tan wire are the 2 im not for sure about because ones the low beam/outside wire for a composite assembly and the other is the high beam/inside wire
