Screwed into a paint free part of metal,perferably a location won't get hit by objects in the trunk moving around. Alot of factoy ground are behind the carpet under the tail light area.
No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in..
Connect the ground wire to the metal box.
to hook up the tach use the hot lead on the disributor and to any good ground wire and if there is a light hook it to the wire on you light switch
Run an amp wire through the firewall, under the carpet into the trunk, run a remote turn-on wire from the head unit to the trunk, and run your RCA's from the head unit to the trunk. Make sure you have an in-line fuse big enough no more than 12" from the battery on the power wire. Find a good ground in the trunk, or drill a hole and ground it under the car somewhere. Hook everything up, and keep the volume down until the sub(s) are broken in. Then feel free to bump!
on my older jvc its no problem at all just ground the wire that your radio says to hook up to the ebrake. newer ones and like my pioneer need to have the radio turned on first then ground that wire. trick is --- get a standard universal relay--- like from autozone for your aftermarket driving/fog lights. take the 85 terminal of your relay and hook it to your radios power amplifier wire(usually blue with white stripe), take the 86 terminal and hook it to ground. take the 87 terminal and hook to the same ground, and finally take the 30 terminal and hook it to you radios ebrake wire. simple :-)
No, the common wire (often labeled as C) does not hook up to ground on a thermostat. Instead, the common wire provides a continuous 24V power supply from the HVAC system to the thermostat, allowing it to operate properly. Ground connections are typically separate and used for safety, while the common wire is essential for powering the thermostat's electronic components.
hook the ground wire to a good ground and pierce the wire you want to check with the tester, if it lights up, it has power, if not it doesnt.
You could, but if you're going to do that then why not ground the entire service entrance panel? ...and you need to drive (if I remember correctly)...about 7 feet into the ground to be effective.
There should be a black ground wire in the Chevy Celebrity radio wiring harness. If for whatever reason that is not available then simply hook a wire from the metal shell of the radio to a convenient point on the dashboard near the radio. I would use a convenient bolt or screw if at all possible.
black and red wires are hot,blk wire to wire junction and brn t/lamp wire cut in,red to batt pwr,blk/w wire to ign turn on and ground to ground..
Hook up the red wire to the fuse box or another wire that gives power when the key is on. Hook up the white wire to a wire coming out of the headlight switch. This will make is so that when you turn your headlights on, the light will come on on the tach. If you don't mind the light on the tach being on all the time then just hook it to another power wire. Hook the black wire to a ground like a screw or a bolt. The green wire is the signal wire. Run it through your fire wall. Hook it up to the negative side of the coil. There will be a negative sign on the coil denoting the correct side.
you could have a bad ground wire that was my problem
