I change distibutor cap and rotor and the plug wires. Now i dont know what wire goes were(exactly). I need to know the firing order on the distributor and on which one it starts on.

87 and earlier trucks =1-6-5-4-3-2 goes clockwise starting at the terminal closest to the number 6 cylinder.

88 and later trucks (w/TBI) Starts with terminal closest to number 5 cylinder.
