welcome to wacky Wednesday's, where everyone has a chance to show off their
car mods, and here's this week's winner, I've got a cool little wiring tip for
you guys that run either a line lock or a trans break when you drag race your
cars,
today I want to show you how I wired up the line lock in my Nova for when I go
drag racing, now my line lock came with this red light and you're supposed to
mount it on your dash somewhere or drill a hole in your dash and it illuminates
when you activate the solenoid that activates the line lock, now I didn't
want to drill another hole on my dash, so I used something else, okay so this is
the instrument cluster in my Nova, on the left you see the generator light for the
alternator and the battery, and on the right you see the brake and the oil light, now the
brake light is what I'm going to worry about right now, because it's used for two
different things by GM, one if there's a failure with the master cylinder or if
you have the parking brake on, now I'll take the parking brake off, and light
goes out, so since GM used this same light for two
different things, I'm going to use it for a third, I'm going to use it to let me know
that my line lock is on, okay this is the parking brake underneath the dash on
my Nova, it's a foot pedal and here's the switch right here, this is the
power supply line, power comes from the fuse box to this switch and when it
grounds it operates the light, so I'll put the parking brake on, and see how
it grounds there and it illuminates the light in the dash, so I'm going to take
power from here to sent to the switch at the shifter, so what I did was I took
this line off and I've got one of these
adapters that has a female end with two male ends, that you just put on the
switch, like so, take the original power wire, connect it so the power is there
and then I had to run a new wire that goes to the switch at the shifter, since
this is powered, this new connector is also powered, and I put the new wire on
here, power now goes to the shifter through this wire, and when I push the
button on the shifter, it grounds the circuit turns the light on in the dashboard
just as if I put this parking brake on, all right here's the instrument cluster
on my Nova again, generator light is on, oil light is on, because the engine is
not running but the power is on, and you see the brake light is out because the
parking brake is off, now what I'm going to do is I'm going to show you when I push the
button on the shifter, you'll see the brake light go on and if if I'm lucky
enough you'll actually here the solenoid in the line lock go on
and off, so now I know when my line lock is applied and when it's released, okay I
hope this wiring diagram helps explain a little bit better what I did
you've got power going from the battery to the light in the instrument cluster
and then down to the switch at the parking brake, now again this is a fully
hot wire all the way down to that switch, so I spliced off the switch where it's
still hot, sent it to the shifter switch from the shifter switch to the 86
terminal on the relay, then the 85 terminal is what is grounded and that is
the signal switch for the relay, now power to operate the line lock comes
from the battery through a four in fuse to the number 30 terminal on the relay
and then goes out the 87 terminal when power is applied to 86, and then that is
what operates the line lock, and like I just said, this doesn't have to be just
for a line lock, you can do this if you have a trans brake as well, they both
operate on the same principle, so even you guys that don't have Nova's, you
could use it on your emergency brake that's in your console that you pull
with your hand, a lot of stereo systems will use that same line to tell whether
your car is in park or the brake is on, so it'll operate the DVD player you know
what I mean, so you could tap it the same exact way, I hope you found this video
informative, get some use out of it at the drag strip, as always happy motoring
well that was this week's video and to have your car mod shown on my channel
here, check this out, so if you never want to miss another one of my new car repair
videos remember, to ring that Bell!
