Not if you want it to work correctlty.Can i hook up both 12v ignition and 12v constant to my igniton wire on the harness instead of using the 12v constant of the harness? I just dont want anything to be draining my battery while the car is off.
The 12vIGN acts as a triger to power up the device, which gets its power from the 12v constant line.
That's really pointless.Also, if i can hook up both 12v to the ignition on the harness will i be better off using a relay and using the igntion wire on the harness as a trigger?
No, you're not putting too much sctrain.Since i will have amp, dsatx and hd radio on ignition on harness. Will there be too much strain on the ignition and am better off using a relay?
All three of those devices are only using the ignition line as a trigger. They are drawing a negligable amount of current.
