76 wiring harness has a "rev limiter", Why? Will the car run without it? Options

[computers4kids]

I'm preparing a 76 2ltr for installation. The smogged has been stripped off and placed in a box for safe keeping.

The wiring harness has a "rev limiter' device that pulgs in on it (75 and 76 cars). The name implies what it does...I think. Why would you want to limit engine revs, unless you are renting a U-Haul truck.

Do I need it to run...can I alter it or leave it off?

In the 75 dealer service and training guide it says USA & CA models were equipted with this item. It says this relay does the following:
1. Fuel cut-off in pulsed operation
2. Speed limitaiton by distributor rotor.
2a Speed litimitation by fuel cut-off triggered by an additional rpm switch.
1 & 2 apply to all USA. 1 & 2a are for CA.
As for the fuel cut-off, I was told it was in case of accident the fuel pump would be shut down to prevent fires. The speed limitation was to replace the expensive rev-limiting distributor rotor. Lastly the part number the dealer service guide says the part number is 039.906.021A

So, do you need this item? Probably not. It looks like it was for safety requirements only.
