Re: Project Unicorn - a light duty trail rig

I left myself a foot or so, and i have butt splices if i need them.

It looks like most OEM's put it in front of the radiator, so its always drawing in outside air. I would have thought you'd get too much ambient heat there, but maybe I'll try it.

Re: Project Unicorn - a light duty trail rig

I mounted mine on the lower part on front bumper with the licence plate mount blocking sun, snow, rain, etc.
When traveling slow and the electric fan is running some warm air is actually coming out in front of bumper.
I need to eventually remount mine to in front of radiator.
This may be what you are experiencing also.

Re: Project Unicorn - a light duty trail rig

I wonder if you're getting some air circulating into the low pressure area behind the bumper there, coming through the radiator then swirling down and forward. My chevy has the sensor in the grille ahead of the radiator, seems pretty accurate.

Re: Project Unicorn - a light duty trail rig

I like the sensor in front of the radiator and low. I'm more considered about temps near the road. They can be very different than a few feet up. Being Texas we hibernated if it gets below freezing. Cars actually run at those frigid temps? I didn't think it possible. I also like seeing road temps during the summer. Its the reality of what your drive train and A/C are contending with. A 100* day can easily be 105-7 near the road surface on the drive home.

I'd been meaning to call you and ask where the chevy's sensor was, as this is a mirror and sensor out of your same truck.

I guess its time for a relocation project.

Re: Project Unicorn - a light duty trail rig

Sitting in a drive thru this week the temp on my mirror read 107. It was mid 70's out, i had the windows rolled down and was comfortable.

Definitely getting engine heat on the sensor. Moved it to the grill today, we'll see how that works out.



Now i just need Mark to come over and drop a tune on my ECU bringing the fan on temp down, so that its running all the time and keeps air over the sensor.

Re: Project Unicorn - a light duty trail rig

Your thread is dangerous for my bank account. I've been looking at the Gentex mirror upgrade for years. Recently had an ongoing issue with my rear view mirror falling off and that was a perfect excuse to buy the 261 and harness.

Re: Project Unicorn - a light duty trail rig

I have the gentex on mine.....only complaint is the mirror is so heavy, it took multiple attempts, and finally having a shop glue it on, for it to stay more than a few hours.

It would help if you work the adjustment mechanism a good bit before putting it on, so it's not so hard to move.

I also sometimes get increases in temp when sitting at a stop light, or when the front of the jeep has been in the sun, but once I am moving again, it comes back down.

Re: Project Unicorn - a light duty trail rig

I had no such problem with mine. Stuck it to the factory mount, its been fine. Adjusts easy?

Mine is used off of ebay though, so maybe already worn in?

Just wait until I get over my indecision on axles and tires.

Still up in the air on:

30/44, 4.10, grip-pro limited slips, chromos, 31/32" tire, stroker

hp44/hp60 from 4643, detroit/arb, chromos, 32/33" tire, stroker

JK Rubi 44 front/rear, JK lockers, 33" tire, stroker

I can make strong arguments for any path forward.

Re: Project Unicorn - a light duty trail rig

I'm leaning toward Wagoner D44s, 5.7l V8, 765r4

I have had a similar issue with lightweight mirrors as well. Multiple attempts to stick the wedge back on with different mirror adhesives failed.

I finally gave up and put it in place with JB Clearweld. This was two days ago.

My mirror is brand new and stiff. No problems. I even went a little nuts on the stress test and hit the mirror, hard. Several times. No issues. The mirror is still where it belongs.

JB Clearweld is what you want. Best guess with the old adhesive kits is the bean counters have all raced to the bottom and we are left with a product that does not work.

I even have a thread about my issues with the adhesives. I have replaced my rear view something like 6 times this year. 3 in the last month! The first of those was after having an auto glass professional install it.

Screw all that nonsense. Get yourself some JB Clearweld, duct tape, abd a popsicle stick. Scrape both surfaces. Sand the area the wedge attached to. Take the duct tape and attach to the off side of the wedge, put a thin layer on the business side of the wedge, and stick it in place. Cover with duct tape and press hard for a few minutes. Come back in an hour. You're done.

Re: Project Unicorn - a light duty trail rig

I'll keep that in mind if it comes off again, but since the glass shop put it on 3 yrs ago, it has stayed put.

Actually, may have to use that, as I need to replace my windshield from some dirt getting under the wipers.

Re: Project Unicorn - a light duty trail rig

Well, direct sunlight has it reading 20* high until the aux fan kicks on or I get over about 25 mph. I may have to build a bracket to suspend it further back in the grill in front of the mechanical fan.

Re: Project Unicorn - a light duty trail rig

Please keep us posted on your experience with this. I bought my mirror and harness piecemeal off ebay. 75 bucks. I just received the harness Friday, I'm going to hold off installing till I pull the headliner.

Should be noted, this is not going in an XJ. It's my S10, see sig. I have to pull the headliner to rebuild /recover it and start building an overhead console. In the interim I will run quite a few wires for overhead switchgear and a few dash toys... Dashcam, radar detector, front and rear cameras (truck has in the neighborhood of 11" lift, near sight lines have gone to shit), and maybe some RG cable for comms (I'm a HAM Op). I have every intent to duplicate the efforts in my son's 97 XJ, wife's 94 ZJ, and my 90 XJ, however.
