OK I got an SLP line lock and I have in installed. If I use the switch that came with the line lock it works fine. But I have a HSW switch plate http://www.harrisspeedworks.com/shop...cat=320&page=1 and I wanted to use one of the switches in this to turn on my line lock. I guess the switch in the plate does not flow enough current in order to turn on the line lock itself. So I got a relay and wired in the relay and it still doesn't work using the HSW switch plate but will with the swtich that came with the line lock. I have tried all 4 switches in the switch plate and none of them will work. I don't want to use the toggle switch that came with the kit because I want to keep things hidden. What can I do know.

 

I haven't seen the SLP switch. Is it just a simple SPST switch (only two terminals)? I seriously doubt the problem has anything to do with current flow. Afterall, a switch just makes or breaks a connection - if there's too much current something will melt or a fuse will blow but it wouldn't just restrict the operation of the accessory.

I'm wondering if you aren't using the correct terminals on the HSW switch. It looks like they are illuminated switches so they have three terminals. The terminals should be marked power, accy, and ground (if not then usually the two terminals in line with each other are power and accy with the one beside the third terminal being the accy one). If the switch goes on the power side of the line lock (i.e. power goes to the switch first and then to the line lock) then connect them as labeled. The ground is only for the switch illumination and is optional. If the switch is on the ground side of the line lock (i.e. power goes directly to the line lock and then through the switch) then you have to reverse the switch connections. The line lock wire will go to the switch terminal marked power, the power wire will go to the terminal marked ground and the ground wire will go on the terminal marked accy. In this case the power is only for the switch illumination and is optional.

 

The SLP swith is just a 2 terminal switch. the Harris swithes are a 3 terminals. The guys from harris told me that termial 1 is the 12v, 2 is the pass though and 3 is the ground. My switch is on the ground side of the line lock. I had it wired up that terminal 1 was the hot wire from the line lock and 3 went to ground. The switch would illuminate when I turned it on. so I thought maybe I had a issue with it not drawing enough current so I wired in the relay so that when I fliped the switch it would comlete the circuit through the relay and should turn it on and it still didn't work.

 

You've got the switch wired wrong. Since it's on the ground side of the circuit, terminal 1 to the line lock is correct but you need to wire terminal 2 to ground. Then, if you want the switch to light up, you'll have to run power to terminal 3 (the switch will work without this but it won't light up when on).
