Got this job done today!
Special thanks to carbuff, salad, dmill89, F1addict for their patience and explanations.

Only a few hiccups.
1) I am not sure where to secure the relays.
2) I don't know if the driver's light is grounded to a correct bolt.

Here is my write-up.

Check that thread for a pic of where most of us have mounted the relays. I mounted mine in the same place, right next to the battery just forward of the clip for the hood prop. I taped the 2 relays together with electrical tape then drilled 2 pilot holes and used 2 sheet metal screws to mount the relays by their brackets. Most of the extra harness can then be stashed almost below the battery out of sight. I purposely wire-tied the fuse holder to the neg bat cable up top for easy access. There are 2 body bolts in the engine compartment on the rad support on either side of the radiator that are popular places to attach each of the grounds.

carbuff,
I've never drilled a hole for a screw to go in.
How do you match screws to the hole you drilled?
Do sheet metal screws come designated with a size that matches a drill bit? (1/8")
Do you use a special drill bit that creates a thread for a screw?

I am going to leave my grounds since the lights seem to be working.

Self-drilling screws are great for grounding. Just make sure you know what's behind whatever you're drilling into!

Do you just hammer it in to get it started?
If I wanted to drill a hole, what sort of screw would I need?

Gee oh Dee

Get self tapping sheet metal screws. They will bite on their own, which should be gathered from their name, but it wouldn't surprise me if it confused you.

"Self-drilling".

That's what they're called. That's what they do.


Self-tapping screws are not the same as self-drilling screws.


Self-drilling screws drill their own hole. Just put a drill on it, with the appropriate bit. The tip is shaped like a drill bit, and it drills its own hole, and threads right in. That's why it's called "self-drilling".

A self tapping screw needs to have a hole drilled. Then it taps its own threads. That's why it's called "self-tapping".

Some people can't seem to understand they are different, but there's a reason they have different names.

Self-drilling screws are very easy to use. Just don't get a 2" screw and run it through a radiator or brake line or wiring harness.

1/2" is fine for grounding.

Here is a pic of my relays mounted.



I drilled very small pilot holes and then forced the screws in while I turned them just enough to get them started. Id say the bit needs to be half the diameter of the screw or less. Just enough to get the tip started. Once youve got them snug there is no need to crank them down. These are the screws I used. I always have a pack of these in the house. I use them for lots of fixes and stuff.

Putting the relays in front of that cavity is not a problem, I guess. I was almost tempted to just tuck the relays INTO that cavity. I'll try that location. Any deeper into the engine bay, and there was no room, b/c of the horn-like thing.

Horn-like thing, in the engine bay?

I think he's referring to the part on the passenger side close to the firewall. Looks like a miniature megaphone.

He is talking about the cruise control servo.Is in front of the battery.
