I recently inherited a Stewart Warner fuel air ratio guage.
Not that it is somthing that I really need, but I do think that It would be neat to add to the dash.
As per the wiring instructions, there is no indication that it should be fused.
Quite straight forward actually- gnd, Power in run and the line to the O2 sensor. The back lighting, is to tie into dash lighting, so thats not a problem, already fused, and will convert to LED anyway.
But should I fuse the power in run line? 5 amps would not hurt, but I'm looking for imput.
Thanks
Pics will come as install progresses.
thanks

its always good to fuse aftermarket accessories

yes fuse it, unless you tap into factory wiring for power, in which case it may already be fused.

Thanks I thought this might be a good idea.
any suggestions on fuse size?
I was thinking 5 amp-

5 is probably adequate and typical for this type of accessory.

5 amp is what we used with GonveVille'* AF gauge installed at NEBF.

Thanks guys.
Pics to follow this week.

The suspence is over....

Installed


At night....and in use


decided to replace the....


O2 definitly was old- and need of replacing


And I almost forgot- found this in the yard months ago, put it on the car a while ago- but temporarly lost the pic in another directory. 80k. and recently replaced. It came from a 92 Regal, but I din't think that its original. And I've yet to see one with a made in the USA sticker on it....

Ahh the infamous blink-o-meter. Nice.

Ya it does blink alot- but I think it looks neat. it really adds to the cockpit feel of the dash.
