anybody else have any further thoughts on this

Re: Mega 450 Wiring Help
 

Just bumping this to the top as I have had no luck at getting this sorted

Re: Mega 450 Wiring Help
 

This is as far as I have got so far, I just don't know what wires to connect to where on the other terminals

I am hopping that somebody can look at my wiring diagram that Clark ( cad ) posted earlier & tell me were I need to tap into

Starting from the top of the mega 450 box

+12VDC: connect to main power supply terminal
Trans: ...???
SFO: ...???
T.Stop:connect to throttle stop solonide
Shift: connect to shift solinoide
GND: Connect to main earth point on chassis
PB 1: ...???
PB 2: ...???
Tap PB : ...???
L L PB : ...???
Tach : connect to Grey on MSD Ignition

I have a pro brake in this car so I will need to push the Transbrake button to select reverse

Re: Mega 450 Wiring Help
 

+12VDC: connect to main power supply terminal
Trans: Goes to trans brake solenoid.
SFO: This is a a multi function programmable terminal. Can be used for starting line enhancer or some other use like line lock. See the manual.
T.Stop:connect to throttle stop solonide
Shift: connect to shift solinoide
GND: Connect to main earth point on chassis
PB 1: Goes to the button that you will use to engage the trans brake.
PB 2: Probably don't need this one.
Tap PB : Allows you to use a button to take time out or put time into the delay or throttle stop during the run (advanced feature).
L L PB : Connect to the line lock button if you plan to use the line lock output of the box (one of the SFO functions). This is also used to arm the data log function of the box even if you don't plan to use the line lock output.
Tach : connect to Grey on MSD Ignition

NOTE: It may be illegal to have the tach wire connected to this box. You may not have such a rule.

Yes you will have to push the trans brake button to engage reverse. Or you can have a separate button for that if you wish.

thanks for that Ricki

thanks for the input guys, much appreciated

I am concerned about connecting the Line Loc to the delay box as I am concerned about its operation when I push the Transbrake Button when I select reverse, if my foot is on the brake & I select reverse then push the trans brake button will it lock the front brakes on ???

here is a much similar drawing
https://dl.dropboxusercontent....0Wiring%20Layout.pdf

I believe I have it all correct, only need to confirm the shock trigger wire ( relay or not )

I have deleted all the other wiring from the drawing & included the delay box

Re: Mega 450 Wiring Help
 

The line lock doesn't activate when you press the trans brake push button. It only activates when you push the line lock button. BTW. All this info is in the manual.

Thanks Ricki

Wiring is not my strong point

Re: Mega 450 Wiring Help
 

do you guys run a switch in the main power supply wire running to the Mega 450 box or wire it to the main power supply & let the Master Disconnect switch shut the box down

is there any advantage to run a seperate switch to shut the Delay Box down with the engine running ect to re-set the box

regards
Rod

Re: Mega 450 Wiring Help
 

I like to have the delay box on its own switch so that I can reset it if need be. I have inadvertently triggered the trans brake switch after the burnout and needed to reset the box.

Also I have had situations where I triggered and released the trans brake switch on the line after the starter halted racing for cleanup or something. I was able to reset the box easily to make sure everything was set.
