fitting a tow bar for a freind,(grand cerokee 2001 ) done the bar but the elecs are hard to fathom out. he got a kit from towsure, twin elecs, found the origonal jeep plug but can only seem to find one feed to the side lights on it. am i missing something . obviously none of the colours match and im fitting a relay box with built in audible warning for the indicaters. anyone got any advice. thanks . alan.....
