71' GTV 1750 spark plug wire order
I know there are plenty of threads on this already but the answers are not as clear as I'd hoped and to someone who is fairly new at working on older cars I was hoping for a more detailed step by step.
So I was checking spark plug wires for resistance as I'm refreshing the ignition system on my 71 gtv and I'm not clear on the order of what plugs from the distributor to what cylinders on the engine. If I understand correctly, cyl 1 to 4 is from radiator to windshield #1 being closest to the rad. The distributor cap is has raised numbers molded into the plastic 1,3,4,2 clockwise with when looking at it from over the passenger side fender.
Firing order is 1,3,4,2 so I need to connect plug wires:
cyl 1 (front near rad) to #1 on the dizzy
cyl 2 wire to #3 on dizzy
cyl 3 to #4 on dizzy
cyl 4 (closest to firewall / windshield) to #2 on dizzy.
Is this correct. I read its possible for the assembly to be 180 degrees around so if thats the case what does the plug wire set up become from cylinder to distributor? I tried what I thought was 1,3,4,2 but it cranked for a bit then popped a loud backfire, I knew something had to be off.
