Gents, swapped out the engine fan and found that the prior owner has cut the plug off on the car side (attached pics)

 

Thinking I’ll cut the plug off of the fan side and splice the wires together.

but which wires go with which?

engine side has brown, red / blue, and read / green.

fan side has brown red / white, red black

 

Also as a test, it touched the brown to brown and the other two wires and the high fan comes on. High fan comes on in either combination (red / blue to red / white or red / blue to red / black…)

last, the wires where getting hot to the touch. Short somewhere? Or is that normal?

 

Normally, brown is ground.

Then, if I remember correctly, the smaller of the two is high speed, the larger is low speed.

(I know it sounds counter initiative, but the high speed doesn't actually need as heavy of a gauge wire because it's direct 12v current, while the low speed passes through a resistor, which in turn generates heat, therefore heavier gauge wire to combat that heat)

​​​​​​ but...
if the resistor is bypassed, then yes, the high speed fan will come in no matter what, since both wires actually run straight to the (single speed) fan motor post resistor. (This is why you can simply bypass the resistor if you don't mind the sound of the high speed fan under low speed fan conditions)

Edit....
I just double checked mine
Brown -to- Brown
Red/Green -to- Red/White
Red/Blue -to Red/Black

 

Yep.
I may not know much - but BlwnAway is correct.
I just did the low speed fan resistor mod a couple of weeks ago.



It may not apply to your fan replacement but the wiring described is correct. .

 

Did mine about 3 years ago...no problems ever since. Helps I am a Journeyman Aircraft Electrician.

 

You can order a deutsch connector, wire that in, and retain the ability to disconnect and have it weather proof.
Or find a junkyard mini with the female side of that connector, cut it off and splice it together -- just make sure you grab the right year, since there's a mid-gen change in the connector

I wouldn't splice it directly together, without the ability to disconnect. You'll run into that problem in the future and curse yourself for not adding a disconnect

 

Thanks for the reply’s my dudes. Big help

im thinking I’ll use this connector:





and this crimp tool:




look alright?

 

big thank you for checking on the wires for me 🙏

 

They'll work and easy to find pins and crimpers locally.

I've done a lot of wiring, and I tend to use these over the GM style connector:

You can then use closed end barrel connectors, that look cleaner and hold better:

Downside, you need a special tool to crimp these... cheap ones go for $30 and only do two different sized barrels:

The pro-tool versions are upwards of $150+


Either way, what you have will work and won't set you back $200 in stuff you might use once. But, if you start doing more wiring...

 

Brilliant. Thank you sir. 🙏

Will update once I get this working

 

can anyone post a link on where to buy one?
about to replace my resistor as well

 

As you wish!
Mouser Electronics.com - ARCOL / Ohmite HS100 R33 J
There is a lengthy thread (if you haven't read it), here on NAM on doing this easy mod.
Works great!
Best of luck.

 

Thank you, I may end up needing that. For now it’s in and working

 

Got it in gents, some photo attached.

I still need to go back and wrap with electrical tape

 

Also plan on testing the fan with inpa

seems to be coming on early (before 105 c)

holding temps at 90 - 92 c (running temp)
