(remove battery power from car before starting if your unsure of yourself to save a airbag or short out )

well have fun on the doors,lol depending on the brand of wire, outside casing thickness 12ga wire even 14ga can be a challenge, there is a punch out on the door jamb side plastic to feed it thru into the main loom. and if you pop the boot off the door side, just make sure you get it back on properly. you most likely will have to cut off some old tape from the factory and maybe slit the boot a tiny bit to get wire thru it. a stiff wire feed helps a lot. old solid 1 piece ford antennas with the top ball cut off work a treat , they can punch thru and stiff enough but still flexable to bend . just tape the other side casue they will shatter a window if you let go of the end while under flex. a fish tape from bunnings works too. (used for fishing wires in walls housing) silicone or talc powder helps heaps to get the wire thru without binding . but its not a fast process .

the wires come out in the top of the drivers side kickpanel, so lots of cuts and scraped knuckles ahead..haha

and make sure the wires go below and close to the inside panel and out of the path of the window regulator , use zip ties and test before putting door panels back on. or the regulator linkage will cut it in half easy

option 2 punch a new hole in door, and jamb with drill and use a grommet boot (same used for power door locks- aftermarket) not reccomended since it can rust, can pinch if done wrong , and still not easy to do

if you have the front fenders off the R34 its easy as hell to pass wires in the car. lol

power wire is easier, follow the throttle cable back to the firewall , in that corner you will see a goldish "cadnium" plated bracket , remove bracket, 10mm bolt i think . behind it is the access to the grommet for power into the cabin. once again a fish tape or stiff wire will be the go, you need to make it arc slighty , cut a small hole in the grommet, with snap knife, pass the wire thru it while taped to the fish tape or ? on the end. use care, now go take the molding off the drivers door sill. and kick panel that cover the fuse box. . you will see the wire come out behind the fuse box area just dont punch thru anything else..lol run the wires away from fuse box, gas pedal, etc. under carpet , under the seat has channels for wire, use them. same for the back seat if its a coupe. stear clear of bolts on seat, seatbelts, yellow wires (airbag or seatbelt tensioner) stay away from all computers in the car and as far from factory wires as you can , cross at 90degree angles , duct/gaffer tape the wire to the floor so it doesnt wander and remember if its huge dont put it in the wear path of the floor , passengers can feel the lump and it will wear thru the carpet where they put shoes. and you dont want to feel it under your gas pedal foot either. , use zip ties to keep away from all pedals

I have 2 0Ga wires run thru mine so you can do it with care, and dont forget to fuse the wire near the factory engine fusebox, no further then that. DONT PUT POWER ON THE WIRE YOU JUST RAN until its hooked up on the other end, or a fire will follow!!! the fuse protects the car, not the amps do not exceed the total amps current draw on the fuse rating.

beware of putting too small of wire for the current load. 4ga wire will handle a max of 120-150 amps but not at 40c+ degrees and continuous it could overheat ?

another hint its easier to power pass wire from the inside to the outside once the fish tape wire is inside the cabin, pulling a coil of 0 GA thru the firewall is a shorter path to the battery then the boot.

wire is heavy and can pull the factory grommet out, which is near impossile on some cars to reinstall..haha

use silicone spray or talc to lube the wiring after you have it taped to the fish tape and keep the lube on the parts of the wire you want to pull thru. clean off with done, silicone can be bad for paint, , or ruin a detailed car.

have fun, if you need more help let me know. cheers

nice to know about the spot for the power cable. we ended up running it near where they installed the alarm speaker which looks like a hole they drilled and plugged.

for the doors we went through the factory plug in the door and found a hole just above where it connects to the car so we used that and sealed it all up.

thanks for the help and fast reply

    • The question then becomes - was there any fluid coming from that hole before you did the rebuild ?    You may not have noticed, of course.   Depending on how you did the rebuild, the possibility has to be considered that somehow (cleaning ?)  fluid entered that hole and is now being 'forced'  out by small movements of the proportioning valve.   From the factory, there's actually a small rubber plug in that hole but with age and under-bonnet heat it's quite common for it to 'go missing'.  That rubber plug is designed to allow the venting process but also to prevent 'stuff' getting to the area (prevent corrosion, etc).   The plug is also not available as a spare part AFAIA. Personally I wouldn't race and buy a new master just yet but keep an eye on the area to see if the 'leak' continues.   If you're concerned about brake fluid damaging nearby paintwork, cable tie a piece of suitable absorbant material over the hole and remove/monitor occasionally.    Operation of the proportioning valve and the brake master itself won't be affected, but also keep an eye on brake fluid level, of course. In terms of a new master, the genuine part is getting expensive, unfortunately.  Amayama is showing AUD900+.   I was searching recently and there's an aftermarket part available from Japan made by 'Parts Assist': https://zenmarket.jp/en/yahoo.aspx?q=BNR32%2bBM50&p=1 Whether it's any good I have no idea, although in my experience Japanese aftermarket stuff is pretty good quality-wise.   The above site allows overseas buyers to purchase stuff more easily from Japan but there are fees and shipping costs, of course.   The original Japanese seller page is here: https://auctions.yahoo.co.jp/jp/auction/p1197401228 Copper/Nickel is fine but I still prefer bundy tube and it's also cheaper.
