I have a 1984 Phazer I got for free after it caught fire, I am now rebuilding it. The fuel line was routed wrong (too close to the muffler) and melted, when It caught fire it basically destroyed the old wiring harness. I replaced the harness and the CDI, I have a spare coil from my 1994 phazer, I know they are different designs but will it still work on the older phazer?
