Wont you just have to extend it? That should be all you have to do i believe....

nope
there are significant differences between a GT4 dash harness(es) and the USDM versions

the AC in a GT4 is all electrical, USDM its not, gauge clusters are different and the way the wires run, and a few other things might be
i really havn't spent time working on the harnesses yet as i'm not to that point in the conversion but i will post up pictures and details later on
(romas might be able to clarify on this more)

Not every GT4 has electrical AC tho. EU and UK spec (at least up to 96) have the same layout and A/C button as every other 6GC.

My JDM GT4 Wreck also had the electrical AC since I didn't want it it saved me alot of work.

thanks for the clarification kadett

so i guess its just 96+ thing on non usdm spec cars?
i just know the actual units are different (the in/outlet) are different angles, plugs are all electrical and a few other bits

You wount be using GT4 hardness thats for sure, cuz this would give you huge headake in rewiring it and etc. You will need to flip over your LHD hardness, but remeber few things - RHD heater core and LHD heater core are different, and you will be installing RHD heater. RHD heater uses 3 motors to control position of the wind, power of the blower, and heat / cold. Your LHD heater has only 2 motorised options (position and Blower) the third (hot / cold air) is controled manualy by the string. You will have to rework the center piece of the heater to control it manualy ( i did vise versa everything... for my it was easyer). Another thing (the MAIN ONE), then you flip the hardness (basicly 2 hardness, one witch goes on the firewall, second under the dash) remeber that the wiring that COMES INTO the car on both sides will need to be extended (left one to right side, right one to left side), you will need to extend every single wire, then run the wiring on the top of the firewall. On the left side there is another wiring that goes to rear of the car (rear lights, fuel pump and etc etc.) this wiring will need to be extended too to run on the right side. Engine wiring (if you gonna place the USDM engine back ofcorse...) will need to be extended too, cuz it ment to be on the right side, and now it will have to run on the left side. You will have to use the fuse box from GT4 (witch goes under the dash) ans there is another box near the fuse box (the grey one) you will have to use it too. Cuz they have different mounting then the LHD fuse box and wire box. There are 2 little boxes on both sides of the car (near the firewall), plugs of the wiring goes to them - you will have to use RHD boxes to plug the plugs in corect places after switching the wiring. Use every single piece witch is on the RHD wiring (all the mountnings and etc) cuz you HAVE TO MAKE THE wiring right if you dont want to have FIRE in your car after rewiring it...

For now thats all - there will be few more issues that i will write about.

maybe some day that car will see the road...

Props for all the work! Seem to be alot it of, you'll enjoy it once its all done!

and this

this seems to be the air intake for the system, coming from the grills under the wipers

yea i know where that tube goes and what its for

thanks for the wiring infor romas i had about 90% of that already squared away but that last 10% defenitly gave me a headstart
and hell no there is no usdm engine going back in...you think i'd do all this and slap a 7afe back in..who do you take me for

one day

Great work dan. Can't wait for you to get this finished. Its gonna be sweet when its finished. Can't wait to see more progress.
