Fitting HZ GTS Dash to WB Ute... Help Needed..

[83 WB_Ute]

Hi guys, I am almost at the stage of fitting my HZ GTS dash to my WB ute.. I know that it basically just swaps over, but a few little things have to be changed..

My question is, what are the things that need to be changed for the dash to function properly?? and an explanation of how to do it would be good, as I don't want to try doing it now and stuffing the whole lot up.. Pictures would be even better..

Also, are the standard WB radios the same as the HZ radios?? I am after one, but can fit a blank off plate if I can't find one for the right price..

Not sure but wouldn't the wiring harness be the main difference and or problem

I have heard that the wiring harness is just plug and play type thing.. lol But I think someone told me that you had to put something on the coil to get the tacho to work and I think that there was one other sensor that had to be fitted for the dash to work..

I will do some searching and see what I can find..

Yeah the pick up for the tacho is a wire from the coil. You just plug the GTS gauge harness into the standard dash wiring but someone said WB harness was slightly different to the HZ one on here earlier. Must not be too different though because its been done a million times. You will need to change the oil pressure sender to suit a gauge rather than a light as well.
As for fitting it, just be careful and patient as they are a bit fiddly trying to hook up the clock and get the blinker lights to all stay in place. Not much extra wire on the harness to play with.

Rightio, it doesn't sound too hard... I should be able to work it out.. Hopefully.. lol

What do you change the oil pressure sender to?? is there just one that screws into the factory spot?? and then does the factory wiring just plug on?? If there is, that would make it heaps easier.. I plan to rewire the whole car at some stage, so I will make it perfect then..

The next thing is, does the wiper dwell switch (I think it's called that..) just plug in on the WB harness, or does it have to be actually soldered in??

Yeah, there is not much wiring to play with behind there.. lol It doesn't help when you have big hands and fat fingers.. lol

I am planning to remove the steering wheel and replace it with the GTS steering wheel, and also put a new indicator stalk in while I am at it cause mine is broken.. :(

Also, how does the horn mechanisim in the HQ-HJ GTS steering wheels work?? I have (supposidly..) all the parts, but don't know how they go together... :( It has a HZ SLE centre cap, does that change how the horn is set up??

Thanks in advance for all the help..

Not sure on wiper dwell. Easier to dash while steering wheel is off. The sender for the oil pressure screwed into the engine block which is just a screw in thing. Wiring is the same.

Screwed into the Block or into the Oil Pump?
Are the senders different for dash with just a light and dash with a gauge? I put a Commodore 308 into my van and the pressure guage goes straight up when you turn the ignition on.(I am having other pressure issues at the moment but it shouldn't be going up to high pressure I wouldn't think.)

Rightio, I will have a chat to the auto leccy friend about the wiper dwell.. Yeah, I have had heaps of trouble trying to do the standard dash with the steering wheel on.. lol And I am not going to risk stuffing up a good GTS dash that I have spent soo much time fixing..

Does the oil pressure sender go into the block, or into the factory spot on the oil pump??

[83 WB_Ute]

Well, I have finally fitted the GTS guages and fitted the wiring up as well. I went to start the car to see if some of them will work, and I established that the battery light works.. lol Bloody flat battery, hopefully I can get it charged up abit tonight and then get the car started tomorrow..

My other question is, when I removed the original WB dash and the wiring there was a plug that came from the fuse box and plugged into the guage harness.. And the GTS dash harness doesn't have a spot to take that anywhere.. So is there meant to be a plug to connect it to???

I have tried looking for a wiring diagram for the GTS dash to find out whether it needs to be connected, but cannot find any..

So if anyone can shed some light on this it would be appreciated..

Wiper dwell is its own harness, and just plugs to a fuse and into the wiper circuit. From memory you unplug a single plug (white wire?) in the harness and the dwell just connects to both plug and socket. Maybe an orange wire down to the fuse box. The main difference is in the binker stalk, so you need to keep the WB one of those.
