Electric gauge wiring
« on: April 27, 2010, 08:33:39 pm »
So i picked up some aftermarket gauges, they just showed up today and now i am wondering if i can use the stock sensors with the gauges or do they have different signals or whatever. I know how to hook up wires and follow a diagram but when it comes the details im a bit of a noob.

I have a vw 1.6td and the gauges are Glowshift heres a link http://www.glowshiftdirect.com/white-7-color-gauges.aspx

I bought voltmeter, watertemp, oiltemp, oilpressure, EGT, and boost. I can make threaded adapters and *** but using the factory stuff would be nice.

As far as which stock sensors are what, the one on the upper rad hose connection is water temp? the one on the oilfilter housing is oil pressure? and the one on the back of the head is for glow plugs and is irrelevant correct? I am also curious as to what everyone is doing to thread in a oil temp sensor it seems there is no extra holes anywhere, so what where would be a good place to thread one in?

Thanks for the response in advance

I purchased the adapter for the oil filter housing from Mcnallyelectronics.com

Easy install: oil psi & oil temp

I drilled and tapped my intake neck ( boost )

Drilled and tapped exhaust manifold , ceramic coated and egt probe is done deal.

I have some 1/4 I.D. black firesleeve for your wiring or you can use some poly sprial tubing for a cleaner install .

I used the 1.6 coolant flanges for my aaz/ MK1 install , glowplug & stock coolant temp

99% of the time, electric gauges come with there specific senders for a reason. i doubt that they will work right if you hook them up to VW senders. you could try it, but dont feel bad if one of the senders cooks your new gauges..

for what its worth im just gonna hook up all the new senders, except for the oil pressure sender i am going to find a smaller one with the same signals, fortunately it tells me its specs on the sender.

why would you even think to use the old worn senders? when the gauges came with brand new ones? i know i know, cause they are already there. but why not have accurate senders for your new accurate gauges?

the main reason is because, when i went to see the thread sizes for the new ones, which are all 1/8 NPT, i noticed that the factory and NPT threads are very similar diameter, and it could cause a headache if i cannot simply drill and rethread the existing holes. i may have to drill all the holes larger with a large thread do i have enough wall thickness for my sensor adapters.

As a data point...stock VW senders are M10x1... most North American after-market senders will be non-metric for sure.

So since i bought a oil pressure and an oil temperature, i need 2 places to thread in my senders. I know there is the filter sandwich thing, but if i move my filter down an inch it will hit my samurai fram forsure. So would it hurt anything to T off of the turbo feed line for oil pressure? since my pressure sender is so big i think i will remote mount it to the firewall or inner fender, so maybe 12-24"s of 1/8 tube. this wouldnt be an issue as far as pressure demands or it would take too long for the turbo to get oil on start up? I might just be over thinking it.

Thanks.

what I did was I went down to the parker store(any industrial hydraulic shop should do though) and got some 10x1 male to 1/8" pipe female adapters.

I threaded the adapters into the stock sender locations and the aftermarket senders into them.

Is your turbo supply line coming off the head or the filter mount ? The mount will see pressure as soon as the engine sees it. That's where I have mine.

What kind of oil temps are you guys seeing ? I've been thinking about a air cooled oil cooler for the summer.

Yup... various vendors make off-the-shelf relocation kits as well if you don't have a local shop... Draft42 has a couple different versions, for example.

the turbo supply line is off of the filter mount. Im not concerned with how to mount my gauges thats all easy. My oil temp is going to go into the factory oil pressure sensor, so i have nowhere for the oil pressure. So if i T off the turbo supply line it will not effect how quickly the oil gets to the turbo on start up? and if it does will it hurt the turbo?
