RE:Help with A/F ratio guage(extending wires)

go to walmart and buy a soldering iron for 10 bucks.


solder a new length of wire onto each wire you have for your af gauge. (same thickness or bigger) then use electrical tape to seal your solders.. each wire should be soldered seperatly.

other than that it is no different than normal.

It would be recommended to use similar/same gauge wire if at all possible. I believe the autometer is 18-22ga. It's recommended that you solder, because you will be running the cable to the ECU.

you can get wire from RadioShack. You could aslo get a soldering Iron there as well.

once you have the wires soldered. Label the ends of your new wires so you will know which one is which. (eg.."purple wire" or "black wire" etc)

Dont cut shortcuts. Solder! Its EASY.


Learn to do it the Right way. The 1st time....

If for any reason one of the wires comes loose and grounds out...your looking at $600 at a minium to replace your ECU.

you can ground it to anything metal attached to the frame of the car. BTW, what kind of "Connector" are you using? A crimp splice? Electrical tape is NOT meant to insulate, its meant to wrap around splices to neaten them up or as a loom or casing to tidy up a bunch of wires into one strand, or as clothing for club goths. Not to keep 2 wires twisted together. After about 9 months, the adhesive will begin to weaken and the tape may begin to unwind itself. especially in the hot summer. Just dont twist the bare wires together and tape around that. at least use some wire nuts (also found at Radio Shack).



what does the autometer auctually read? I mean, how does it know what to display weather its installed in a '99 coug or '03 caddy? Theyre different cars with different tuning specifications. How does the meter read "good mixture" for 2 totally different cars? Is something standardized?

Just like the temp. gauges. I know there are a few different sending units for my MGB, I bought a rebuilt motor and It came with an earlier temp sender, so my gauge read barely off the peg at running temp. The proper sender fixed it but thats '60s technology. Do ALL temp senders now output the same voltage/°F ? or do they come with their own sender if you buy a temp gauge? ahhhhhhh!!!!!
