Is It Possible To Bypass The Loom Plug For A Head Unit?

[D-limo]

My mate has a Pioneer HU sitting around doing nothing.. It has no loom. Can I hard wire it in?

[danielson]

yes but it is much harder than you think.

More info would be helpful

First, go to Jaycar, Strathfield and Dick Smiths and see if there is a harness adapter for your headunit. (from your unit to ANY car harness)

That way, you don't need to make up the plug or solder wires directly onto your headunit, just plug in, and then crimp the other end of the loom to fit the stock harness.

Failing that, I don't know how easy it will be to work out which pins on the back of the HU are for what. A multimeter will only work when there is power applied, and then finding the right pin for power first go sounds unlikely. If you apply power to the wrong pin, you may blow something up. If you open the unit, a trained eye could probably verify which pin is for what, but that's not me!

The hanesses cost like $45.. And the unit is probably worth that 2nd hand.. So yeah I'm trying to do it cheap as possible lol.

You're right. Finding wich pin is for what is going to be the hardest thing to figure out. I was hoping it was that easy. Can anyone confirm? Also is there spec sheet or the like I should be searching for that would contain what each pin does?

You can do it, you have to open the rear cover of the headunint and solder onto the plug socket. trust me mate, not worth the trouble.

If it's not worth buying the wiring plug, then it's not worth installing it like that.

It'll be a shit job. difficult. probably fail too.

tell me what the unit is EXACTLY and I'll sell you the harness to it for $20. much easier than destroying it..

Sounds a bit too mission for my electrical skills (read close to none). Cheers for the help people.

This sounds stupid but can't you just crimp a blade onto each wire and plug it one by one into an existing loom?

blah.

Apparently not :
