Does anyone know what is significantly or fundamentally different about main body wiring harnesses from 1974 to 1975.
The engine harness doesn't count. What's different? Thanks! |

Guesses:
1. The 75 harness would not have the 'Fasten Seatbelt' wiring as in the 74 harness? 2. The 75 Catalytic converter cars (California only?) would have wiring for the cat and dash light...the 74 would not. |

My '75 has the fasten seatbelt light.
And no cat dash light. |

What about the ignition switch? I know the '75 and '76 cars used a VW Rabbit ignition switch. Are the connectors different?

My early 75 had the same wiring harness as a 74 as far as I could tell... including that stupid seatbelt interlock crap (IMG:style_emoticons/default/mad.gif)
Which part's giving you trouble, Karl? |

The connections are the the same. I've put the rabbit switch in a 73 and a 74. It's also about 1/4 the price!

Our good friend George says the '75/'76 harnesses are "significantly different" than the earlier harnesses.
Other than the EGR wiring and the seatbelt buzzer crap (also on '74s), I fail to see what is different between a '74 and '75 main chassis harness. Yes... maybe the wiring order is different, but could you effectively install a '74 harness in your '75 car and have everything work? Everything that plugs into the harness (light housings, switches, door sensors, brake switches, fuel fillers, gauges, is the same). Since I'm not using the relay board, what's the real difference then?... Hmmm???? |

I thought the wiper switches were different? maybe not..
I don't see what could go wrong with using a 74 harness. Geoff |
