Through the big wiring grommet under the hood. After I ran the wiring through. I put rtv over the area to seal it.

I got my relay's in today. I am not sure I will have time to tackle it this weekend. The honey do list is long.

Up-date.

Getting ready to drop the sub-frame to install the SPL bushing in the sub-frame mounts. So I decided to drain the rear diff of fluid. Very pleased with what came out. No particles that I can see. The lube is dark, but not black. Pulled apart the screen filter that I installed in the line that goes from the diff to the cooler. Nothing in there either. :tup: Man.......that OS Giken lube is thick. :icon14: I'm going to leave it drain over night. Oh, there is about 2,000 miles on this lube since I installed the OS Giken diff and cooler. So it was over due for a change.

Can't wait to have mine installed for Zdayz this year.

Damn how often you changing the diff fluid?

Hey rusty you want to install my hood vents later this year. I could use a mini road trip while im up north and good excuse for you to sip on some moonshine and make a few bucks. Plus I could learn a thing or too.

How many vents you got?

Hey Rusty,

I just custom installed mine with your guidance, thanks!
How long does it usually take to cool down the diff temp and what is the optimal temp? Mine has a temp switch that turns on at 180 and I noticed that the pump and fan do run quite often and run for about 10-15 min every time. I don’t have the MMA fan shroud so trying to make sure the ventilation and cooling power is enough.

Thanks

I've seen high of 270F before turning the cooler on. It takes about 10 to 15 minutes to cool off. Think the idea temp would be about 180 to 200F. Depending on what weight lube you use. When you get above 270F. The lube starts to break down and cook.

Hey Rusty! Thanks for the awesome build thread! Just had the Ma Motorsports diff cooler installed but didn't realize it doesn't come with any electrical/switches so it's always on. Obviously don't need it just heading to the grocery store or a quick drive with the kids (not a daily but any excuse to take her out) so I wanted to add a switch. Either one switch for both the fan and pump or one for each. Jon over at Ma mentioned to be careful I get the right amp rated switches but haven't heard back on what amps I need. lol It doesn't look like your thread specifies the amps or notes which switches you used. I don't want to buy ones that won't work or will melt bc they aren't rated high enough. Can anyone point me in the right direction?

Here's the ones I'm looking at:
My favorite and the mounting hole will fit in our little dummy switches above the cup holder but not sure the "paddle" will fit before hitting the mold. Curious if anyone has used these:

or

I know the second ones will fit but want to make sure the amp rating is where it needs to be. Thinking of getting both bc they're cheap enough but don't want to end up where NEITHER of them work. lol

You want to run them off of a relay. Use the switch to energize the relay and turn on the diff cooler fan and pump at the same time.

I used 15 amp switches wired with 30 relay's. One switch and relay for the fan, and one switch and relay for the pump.
