Either way will work right?

Well, since Dubulup took the time to make a diagram picture, I'll use his way

 

Personally, I like the idea of cutting the signal coming from the ECU...using two relay's triggered by one button. This can be achieve in the kick panel...not in a cramped area in the bay.

Only reason I suggested keeping L & T switch 12V power separate...is for loading, taking away 2/3 load and adding it back, probably isn't that crucial in automobile applications.

 

I'm just going to run it like you have here:

 

i can help u its pretty easy i have mine all wired up through the clutch switch. does the 3rd gen have a clutch switch like the second gens? I can draw u a picture if u want. if no clutch switch then horn or any type of switch could be used.

 

I'm just going to use the horn button.

 

Alright, I hooked up the relays today. I've got a problem though. When I hit my horn button, it powers up the trailing coils. When my finger is off the horn button, I've got no power to the trailing coils.

Basically, it's doing the absolute opposite of what I want it to do.

This is how I hooked it up. I want power to my trailing coils all the time except when I hit the horn button. I want power turned off when I hit the horn button. What can I switch around to make it right?

 

Trail Coils PWR wires on 87 instead of 87A

 

It's as simple as that?

You the man, Thanks Partner!

I'm using a 8,200 pill for my high side and a 8,000 pill on my low side. This should crack some windows!

 

keep us posted

 

any testing yet?? when you have everything sorted out you should donate a write up in the drag racing section....

-dj

 

I won't have a chance to finish it until this weekend. I'll do a write up when I'm done.

 

eh I might as well just installed my haltech e8 - but if your way works well, let me know bro.

 

Instead of using the horn to trigger the relay, use the clutch switch. That makes it automatic and sets up the two-step for full-throttle upshifts

To do this, connect the blue/orange wire of the clutch switch to the 86 terminal of the relay. Everything else stays the same.

 

It's already hooked up to the horn button and will work great if I ever throw an automatic in.

 

Dude, I'm still doing something wrong here.

Having it hooked up the way you told me, I am getting 12v on both 87 and 87A when 86 is grounded.

So, basically I'm not getting 12V until I ground 86.

_________________________________________ just to make sure, I've got two leads on my horn button. I'm running a wire from 86 to one horn wire and the other horn wire, I'm grounding it. Is that correct?

Do you have any ideas?

 

Could my problem be that I am using "Normally Open" relays?

 

are you using the relay from post #3? that one has both 'normally open' and 'normally closed' terminals. the correct terminal for your case is 'normally closed' which is 87a. post#20 is the correct way to hook it up.

 

Alright, I need to seriously lay off the booze.

I've been working with normally open relays this whole time. I went and bought some normally closed relays and hooked them up. Guess what, they work.

I thank the lord, time for another beer.

 

You're an idiot.

Good luck, and let us know how it turns out =)

 

Yeah, I know......

I've got the trailing coils turning on and off and wired up. Going to wire up the 2 step box tommorow morning.

 

Wrong.

I have a tecIIIr, the two step works just fine with both coils working.

 

I know, I said this is the only way to get it to work without a computer that supports it. Your computer supports it, mine doesn't.

 

Well, I got it working...........and hooked up. I might try it out tommorow if I'm not too scared

 

Chicken!

Try it at lower rpms at first. Like 5K rpm.

 

Yeah I know, I've got a 3k pill that I'll toss in there to try it out.

I decided to hook it right to my clutch switch instead of my horn button.
