Need 12V switched source in the eng. compartment

I have a 1987 Carrera. I just installed a MAF which requires a 12V power source. I need a source which is switchable (only hot when the key is on) I found a 12V source using either of the three fuses on the posterior, left side of the engine compartment. However, these are hot all the time. I find the MAF draining power while the car is sitting.

Need help, Thanks

I needed a 12v switched source when I installed a shift light a while back. I ended up pulling it from the fuse panel up front. I realize that is from the wrong end of the car but it may save some time and frustration if you have not solved the problem yet.

Good Luck~

The heater blower fan only works when the key is hot.
