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

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.

      Started sifting thru my brakes to decide which ones I will run on Clem   Made me think I should just put them all on Silver...for when brake fade just isn't an option   Should be able to bump rotor up from 343x32 to 348x36 off Supra. Not sure if the Supra annulus is right for the Alcons or APs but trying g to find a used Supra\M4 rotor to test fit The Alcons seem to gain 1-2mm clearance which all helps

      HR34 GT speedo issue

      Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.

      Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way

      Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate
