==HJ To HZ Dash Conversion:==

===Details:===

Here's how I converted my HJ Dash to a HZ one, because I don't like the original HJ dash. I am also going to install the HZ indicator stalk, so I can remove the HJ highbeam switch and the wiper switch.

Note that I have already moved the speedo cable. On the HJ it comes up to the dash in the center, but the HZ needs it to be on the right hand side. I did this by pulling the cable from the engine bay until the end hit the firewall, then pushed it back up into the righ hand side. The HJ Dash wiring loom is also removed. This is all from one big black connector on the right hand side of the steering column. It usually takes a bit of pulling to get them apart.... Click to Enlargen. Photo by Hairy-Dude.

 Here's why the yellow Wire was cut ....

The HZ dash wiring plugged straight in, but I had to do one modification. The HJ uses a single warning lamp for handbrake and brake fail, whereas the HZ uses two separate ones. So here's how I fixed it - on the wiring loom for the gauges, cut the yellow wire shown in the above photo (the one at position J on the plug), and extend it using another piece of wire so that it reaches around past the fuse box and down towards the door. Cut the black wire from the handbrake switch where it joins into the loom just near the front of the door, and join this to the extension from the instrument loom.

There is also an orange wire coming from the HZ dash loom. This is to power the clock on the dash, and has to plugged into the fusebox. This is done easily by removeing the two screws from the top of the fuse box, and moving the fuse box down. The terminals on the back of the fuse box are numbered, and you need to plug the orange wire into position number 5. Note there is a ground wire to re-attach when re-installing the fuse box into position.

Then it is just a matter of putting on the dash facia, lower dash facia and glove box panel, and you are set to go. Note that if you are not changing the dash pad, you won't need to remove the glove box panel in the first place!

There you have it, a fully functional HZ dash in a HJ. In case you are wondering, yes, the speedo is not the standard HZ speedo. I bought a GTS dash for my other project car, and this speedo came as an extra. It's not a GTS speedo as it does not have the highbeam and indicator lights in it, but fits in perfectly into the standard dash with no modifications needed.

Soon I will install the HZ indicator mechanism into the HJ, and I will put the details on this web site also. I hope these will come in handy for someone!
Cheers,

Hairy-Dude.
