uncrossing sparkplug wiring 79 ChevyOne good way to uncross the spark plug wiring is to find out what the firing order is for the engine generally can be founf in the owners manual or embosswed on the intake manifold you can also find the firing order on a plate or sticker under the hood or in a Haynes repair manual for that car you will then need to determine which is the number one through n n equals the number of cylinders of the engine probably 8 in your case then trace each wire back to the distributor the numbers are also on the distributor cap clockwise make sure the wires on the cap go to the correct spark plug 1 to 1 2 to 2 3 to 3 etc. uncrossing sparkplug wiring 79 ChevyOne good way to uncross the spark plug wiring is to find out what the firing order is for the engine generally can be founf in the owners manual or embosswed on the intake manifold you can also find the firing order on a plate or sticker under the hood or in a Haynes repair manual for that car you will then need to determine which is the number one through n n equals the number of cylinders of the engine probably 8 in your case then trace each wire back to the distributor the numbers are also on the distributor cap clockwise make sure the wires on the cap go to the correct spark plug 1 to 1 2 to 2 3 to 3 etc.

assuming its an 8 cylinder 1-8-4-3-6-5-7-2 looking at the engine from the front - right bank is 1-3-5-7.left bank is 2-4-6-8 pull #1 plug bring it up to compression stroke now take your cap off rotor should be pointing to #1 on the cap follow the firing order and direction of rotor sounds a little long but if not noted on cap that is your best bet
