I need a wiring diagram for 1972 dodge truck


Mate this is a link to a wiring diagram for 1972 dodge challenger, They're saying It is wise to first read to understand the wiring schematic before making any wiring changes on your Dodge Challenger to avoid any wrong wiring connections. By-the-way, you can clink on the diagram to enlarge the image and clink on it again to see which wires are the right colours, CHEERS..

Where is the paint code on a 1978 MGB


The VIN for the later MGB circa 1970 to 1980, may be found stamped on a plate secured to the left hand door post, and on a plate secured to the top of the dashboard.

These colour codes maybe useful -

I connected the wires to the head light switch on a 72 mgb and the black wire melted real bad. How do i find out what wires go where


You need a wiring diagram. Use a multi meter to find which terminal on the switch gives power (12volt) black wires are always negative (-) SO WILL BURN IF CONNECTED TO POSITIVE (+12V) supply.
