Pre-1980 911 fuse question

WJG2 · WJG2's Garage

I was given a car alarm called The Electronic Cop which appears to be a good system. The problem is that the company has gone out of business (Hmmm, maybe it wasn't that good a system...) and the instructions don't cover pre-1980 911s. Mine is a 77. The package comes with the newer style two-prong glass fuses, while my car has the old style, torpedo-shaped filament fuses. For years
1980-86, the instructions say to use "power fuse No. 18 in the engine compartment and fuse number 16 as the interrupt circuit." Can anyone out there
advise whether it's possible to adapt these instructions so I can install the unit in my car? Thanks.

Any Western Auto/Autozone type store sells a mini fuse block that you can wire into your present system and it has one or two of the two prong fuse outlets. Really simple to do.

Thanks for the suggestion, but I live in Canada and was hoping that another Canuck/1977 911 owner might reply.

They don't have auto parts stores in Canada?????

OK, OK...Yes, we do, but I guess I should have worded it a little differently, something along the lines of hoping that someone who had done the procedure would reply! Thanks for your reply, by the way.

Not sure what you are trying to explain about the fuse, but maybe I can provide a little info.

Your car alarm needs a power supply and in all likelyhood there is a fuse inline for that circuit. If what you have is a two pronged fuse holder and no fuse, then you can purchase them from auto parts stores. If you have the two pronged fuse but no fuse holder, then get rid of the fuse and install an inline fuse holder (glass type) with fuse on that circuit from auto parts store also.

I have installed an alarm system on my vehicle that I had purchased from a discount supply house (pawn shop). Installing a car alarm on a P-car is a little more difficult because you have to know what each fuse in the fuse bank is for and which wire from the alarm system goes to each fuse, or to a ground wire.

I am not sure if this info helps but if you can provide a little more info maybe I can be of further help.
