factory tach???
factory tach??? well almost, started out doing the camaro tach fuel gauge thing to my electronic speedo, didn't like the look of it, so bought a little tach from princess auto, with a shift light, took it all apart, made it fit behind the original gas gauge, installed the smaller maro fuel gauge, got a local decal place to make me a new front for it, and then installed factory needles to finish it off, also installed a factory clock. Not as easy as it sounds, had to remake the hole original housing, and printed board, but it turned out pretty good, and now I can use the 4cyl mode

Re: factory tach???
sorry no pics, it was a real b!tch, had to cut apart another housing to make it deeper under the tach for clearance, could have just cut a hole in it, but had more time then that so... lol... then had to cut the printed circuit, moved a bunch of wires around, by re soldering, and extending them because of clearance issues, the gauge was from an electronic speedo truck, and getting put into a 76, so the plug in wires had to be moved around on the truck side to match up with the newer style gauge, also had to run a wire for the oil pressure gauge

Re: factory tach???
uugghhh! all that work, and I can't get it to work???? it worked in the truck I pulled it from, and now there is nothing?
so I went and did some research and I might need to wire in a resistor. Will let you know what happens... Last edited by bark; 05-29-2012 at 12:43 PM. |

Re: factory tach???
Most '03 and newer PCMs will need a pull up resistor, a 680 ohm 1/4 watt resistor placed between the power and signal wires on the tach.
