hey all, if i need to manually wire my headlights for a night race... what's the safe way to rig that up for a couple 20 min sessions ? can't find my headlight / turn signal switch, so that's the key challenge...

travisjb · 04-10-2010, 12:28 AM

here's the headlight swtich diagram on the BCM... assuming i can just connect a few of these together... will give it a try

First dibs on the headlights and taillights if you decide to sell them

I'll need a spare set to pass inspection one of these days

Looking at that diagram I agree - looks like you're good to just complete the circuit.

Someone may as well order Travis another ECU while we're at it

Just kiddddinggggg....

It's a 5x5 matrix yielding 20 different combinations of connections. The output transistors are turned on one by one (ground reference) to sense which inputs are active.

But basically if you wire INPUT 2 to OUTPUT 5 via a switch with an in-line diode you will activate HEADLAMP 1 mode, and if you wire INPUT 3 to OUTPUT 4 you will get HEADLAMP 2 mode. I don't know what is different between these 2 modes so you will have to test it.

For those trying to turn on the voltage signal to the fog light it looks like you can wire INPUT 4 to OUTPUT 5.

There are no specs on the diode shown but it doesn't look like it is doing anything special other than regulating current flow in the right direction. A IN4001 (available anywhere) should do the trick.

A great electrician/ECM technician is worth $1000 a pop! Thx for your input, chrisslicks!

good explanation chris... i got it working last night by simply wiring 2-5 to a switch and 3-4 to a switch... interestingly, they both seem to do the same thing = low beams... you run either or both and LOW BEAMS... no idea why that is...

By the way, the numbering on this matrix is different than the pin numbering so for anyone using this chart make certain to look up connector number "m33" for an explanation of how the I/O maps to the pins

Also, I didn't use diodes... is that bad?

The diodes are a safety to ensure that current only moves in the one designated direction. I would add them to prevent the chance of damaging the BCM. Just make sure it points from input to output, i.e. stripe side facing output.

I ran against Chris Rado tonight... nowhere near his speed, but i had a blast... went off once, but car is okay beyond some exhaust hangar repairs that will be needed... will up some video to my vid journal in a few, assuming it turned out okay

Brazilbro · 04-11-2010, 02:12 AM

heres some fender vents for ya

travisjb · 04-11-2010, 03:44 AM

interesting... perhaps robi can shed some light on this design and provide more pics?

Bluemeanie · 04-11-2010, 09:22 AM

Hey Travis, you wouldn't happen to have a complete torque spec sheet or know where I can get one for the 370 would ya? You can PM me if you like.

travisjb · 04-11-2010, 12:11 PM

Hey there, no I don't. But if you find one or put one together, would be helpful to start a post here on that topic. Might have to piece it together from service manual (Torque Specs).

So, are you by chance rebuilding the motor?

Not yet. I have the Rotrex SC but I'm rethinking that vs. going NA. Right now I'm just learning how to become a better driver. I think a Motec is in the cards for my next mod.

Thanks for the link by the way
