Need to know which does what.


Thanks in advance!

Rashy,,,,
Red-- 12 v power
black-- ground
green -- coil negative
blue -- dash lighting ( most guys pair this with red so the light is always on )
If you want it to dim with the dash lights find a dash light to tap into.
Pretty much universal color code.
