Hello guys,

I am building a car with all '74 2.0 injection parts, except the ignition harness that looks to be a 70-71 1.7 ignition harness. I think it is a 1.7's because it has a heater ground terminal that we don't see on the 2.0's harness.

The car stars and runs. But is there any problems if I continue using it with other 2.0 injection components? I may be wrong but the 1.7's positive wire to the ignition coil looks to be thinner than the 2.0's positive wire.

Thanks in advance for your thoughts!!

It'll work. The big issue is the two circuits for the heater are not in the correct location for a '74 chassis, so no heater fan without reworking the harness.
