Stupid question

[tomsC10R]

I'm trying to find a spot to mount my computer for my fuel injection. The only out of sight spots I can find is directly to the bottom of my dash (would need to drill wholes from the top) or mount to the backside or bottom of the cowl inside the truck (the canal where air flows for the heater and WATER runs off)

Has anyone ever drilled holes there. Is there any way to seal up the wholes well enough to prevent water from leaking inside the cab and more importanly on to my computer? I was thinking of some kind of silicone... Am I asking for problems? Should I just drill some holes in the top of my dash? Or should I just mount it on the kick panel or any other suggestions?

Oh yeah, the computer is 10 x 6 x 2 inches. Any ideas?

Thanks in advance

Glove box?

I mounted the computer to the underside of my dash with heavy duty velcro. Not sure how well it will last long term, but it's held up for about a year.

MrGoodpliers,
I had thought about that, but the glove box is only a cardboard material. This computer weighs at least close to 5 lbs. Wasn't sure if the glove box would hold that up, I know the old one wouldn't I would need to mount it down somehow too... You can't buy replacement glove boxes made of metal can you? That would be perfect Somebody want to make one

bpmcgee,
I'd be afraid of using velcro.

Any other ideas or opinions on my first idea?

Thanks.

I have heard of people putting it under their seat, but not sure if the wiring harness is long enough for you.

I built a rack to mount my ignition computer and 6AL box under my glove box.

Pulled the cardboard box out and built a rack out of .060 alum. And some alum. Angle. One end attaches were the hinge screws go for the glove box and the other attaches to the section were the cow is and sealed the screws with aircraft fuel tank sealer. This gave me a good solid place to mount everything on rubber isolators. Then reinstalled the glove box cardboard and now you could put 10 pounds of crap in there and not worry about falling threw. The boxes are just barely visible while sitting in the truck. I was going to put them in the glove box but wasn’t sure they would get enough air to keep them cool.

Why not build a good tight box and mount it in the engine compartment? When I did my lt1 S10 conversion I mounted the computer to the inner fender well. I never once had a problem with it. Just a suggestion.

71swb4x4,
I thought about it, but I don't think I'd be happy with it like that.

jorgensensc,
That was my plan all along until I read my owners manual.
This is what it says:
WARNING! Do not mount the ECU in the engine compartment or in an area exposed to the elements of wheather or areas that can get wet during use. The ECU is not designed for an environment with signifigant amounts of heat or moisture. Premature failure of the ECU will result.

I'm sure if I made a good enough box, I wouldn't have any problems. But I don't think I want to take any chances, not yet anyway...

Chevy67Tk,
That sounds like a very nice setup you have there. Sounds like exactly what I was trying to think of earlier today Seriously, that would be perfect. That's a good point about heat in the glovebox too.

Where did you get the aircraft tank sealer from?

Could you possibly take some pictures of it for me? If not, that's ok -- very good description. I owe you one.

Thanks again

Your welcome
I can try and get some pictures of it in the next couple of day and post them. The sealer was some that I had left over from my days as an aircraft mechanic. If you have a small airport near by stop and see if they got some it’s a 2 part system some times called fire seal, we used to use it to seal all kinds of stuff.

If you are considering the use of silicone for any type of adhesive, you need to know that there are automotive silicones and the other kinds. Many of the silicone adhesives that you find contain chemicals that will cause rust to form between the two parts that you join. Sometimes, people will use the wrong kind to stop the leaks that they believe are coming from around the windshield. Usually, those leaks are caused by the stuff that has collected just above the kick panel vents and the holes that were caused when the metal rusted through.

So, be careful when you use silicone adhesives, like Silastic for instance.

That would be great.
Thanks!!!!!!!
