X should be 'load reduction' in that mk3 harness I'm guessing. Nice job simplifying the harness and cleaning up all the hack work and fire hazards. Sure beats having the caddy burn to the ground or having to chase electrical issues as they arise. Gotta love some fresh Tesa tape. I de-pin the connectors too, it's the right way to do it and really the only way. I usually run my own 12ga wiring/ 40 amp SPST relay for my fan(s.) Much more reliable that way, and you can optionally add a 40 amp toggle switch to override the fans when you want them to run without the thermoswitch deciding for you. Nice work, this thing is gonna be a nice reliable daily when you get it all sorted out. 👍✌️
@@SmithsEuro Yeah I wasn't saying in particular in the mk2 or Volkswagen in general application wise as far as the relay goes. It's just how I do it on my E30/ E36 track cars and some others. Plus on the mk2 and up you have the whole fan control module so definitely no need for the relay. Wish I was closer to you, I'd love to come by and turn some wrenches. Met so many cool people in the Euro car community, from the local clubs and the forums especially. 👍👍✌️🙂
@@SmithsEuro Oh I have gone to H20 in the past a few years. Was Definitely one of the most rowdiest shows I've ever been to! Hell of a good time. I was probably working pretty much every year so I would've had to remember to ask for the time off ahead of time, or if I was in my shop I most likely had too many jobs to put them off and just go, although I have put customers cars on the back burner on the past to hit up the track or go for drives with this euro driving club I used to be in.
On the MK2, they put the radiator fan relay right on the radiator fan shroud. I put the MK2 setup on all my MK1s. Also add a manual fan switch to save yourself if the thermoswitch dies in rush hour traffic. Other than that manual fan switch the radiator fan is isolated from the rest of the harness with a direct connection to the battery. through an inline fuse. That 6-pin grey plug might also provide power to the heater fan relay on high. You need a heater fan relay on high speed or you can burn the switch up.
The 6 pin supplies the power to the fan relay in my wiring. The other 4 wires were all ac related. Temp sensors and whatnot. I like the mk3 fan switch and just 10g power to it fused. Ive had it that way in my mk2 vr6 car for years with no issues. I remember the mk2 stuff in my old mk2, i just tossed it since i was putting in a civic rad.
No they are directly from the fuse box to the battery. Oem “fuse-able link” wiring i cut after that. For the alt you just use everything from the mk3 the 2 wires for the mk1 are underpowered compared to the mk3 stuff

Appreciate it man. I have mine ran that way in the mk2 just directly to oe fan switch with all 10g wiring and a fuse.
No need for the relay.

Why didn’t you come down to waterfest?
Thats probably the furthest north we go at atco.

Youll have to come out to waterfest next year.
I plan to have the 3.6 car there racing.

At 5:26 the two red wires that power the fuse box, did they come from the mk1 alternator connector B+?
No they are directly from the fuse box to the battery. Oem “fuse-able link” wiring i cut after that.
