thanks for all the help everyone. This is going to be the weekend project.

Installing a BadBoy horn. I want to isolate it from the remote so I won't irritate neighbors every time I lock the doors with the remote. Can't program the remote so lights flash with no horn; it's both or nothing. I don't see anything on the horn circuit wiring diagram indicating a lead to the lock circuit so I assume the horn voltage must come from ECU. Has anyone dealt with this?

 

ya know,ive seen relays, most,that are 3/4 in cubes. some smaller, with 1/4 in flat connectors.
i will be real interested in seeing just how 2 pieces of # 8 (yikes!!) will be attached to the typically 1/4 in. faston flat pins,,huh.
sounds like the wire might be bigger than the relay. for certain it will be a mounting problem.
do post pictures!
oh btw i do a lot of wiring,(or i have) and i find that any heavier than 14 is really a lot more effort to handle,strip,bend,attach. you cant usually just do a hookup,ala #14 and stuff the outlet back in the box. it takes some careful bending to make it fit.
lucky, no boxes in the car huh.

 

you can kill the horn. i did it the first day on 2 h3. lites only.

just read your book.

 

Since his current draw can be as high as 60 amps, he's going to need his first relay in the 'T' to be something larger, (80 amp. cap.?) which can now use crimp on ring connectors. THIS is the only relay that will need the 8 gauge, the other 2 can be the '3/4" cubes'. Spooky, I've attached a link of the relay I used for my washer fluid heater (which also is 60 amp).

I do a lot of wiring too. There are plenty of ways to attach multiple 1/4" push-on terminals to the single terminal on the relay.

Here's a couple:

 

Bunger....I played around with some wire diagrams, and if he wants to control all 3 sets of lights independent of each other he won't be able to use the 'T' setup we first thought would work. The 3 relays will need their input power to to be in series, so each relay can be toggled on/off to control it's own lights. If not, then the main relay, when active, will always power the set of lights coming from it's output.

 

lets see,3 sets of lights need 3 relays hooked up with #12 at the max with tiny relay coil wiring. thats about it. not complicated.
no 60 amp welding cables.
when i said 2 #8 wires i obviously meant;one in,one out,not tied together.
#8 is the size of a pencil,kinda hard to work with.

and no,hes not running them for hours on end huh.

 

One last attempt to get through to you tom.....if he has a maximum draw of 60 amps, 12 GAUGE WIRE IS NOT GOING TO CUT IT! Maybe for the last relay in the series, but not for the second, and CERTAINLY not for the first!

 

just hook each relay , one at a time to the batt. with #12 wire

i know, lets play pretend,like in preschool;
on day one we hook up some lights on a 20 amp circuit with a relay.
then we rest,nap time
on day two we decide we want more lights. we go buy them.
on day three we hook them up to a 20 amp circuit with # 12 just like we did on day one.
nap time again.

a week later we want even more lights. ,,,you know the routine. one more trip to k mart , auto zone, but lucky us,we still have 81 feet of # 12 wire left!!
