your choice of wiring kits depends if your restoring or up dating or modifying,,
all non stock fitting after market kits,are GM based,and color coded,,you will need to get a mopar wiring diagram to complete it,the biggest kit painless sells comes with GM,FORD,MOPAR wiring diagrams,,it is not a mopar specific wiring kit,,and will not have a bulk head or wil not appear stock. and it uses a 1980s style GM fuse block,just like all after market wiring kits,,,ron francis has really nice stuff,,there own fuse block,with nice options, i think that is the kit im going to use,,but pricy
if you are using modern head lites such as H4 bulbs you need a relay on the low and high beams,,or you wil sooner or later burn up your head lite switch,,
40 year old factory wiring by now is britel,and wont with stand the modern high out put altenators that are available today,,a retro wiring system and stock alternator will be fine,,such as sold by year one or evans wiring,,
ive been researching this for too long as im an going to rewire my barracuda,and probbaly my street rod,,let us hear what you go with please
