Remote starter install
Hi,
I am just in the process of installing a new alarm with keyless entry and remote start.
In the remote start wiring it says to connect a wire to the neutral safety switch, which is a safety feature.
But after doing some measurements I found out that the starter circuit after the ignition switch gets power in "start" regardless of shifter position.
Of course, it only starts in P and N so the switch is somewhere after the ignition switch.
That would make the additional connection to the remote starter unneccessary in my opinion.
Am I missing something here?
Oh and any good spot to get a signal from the underhood lights would also be a nice piece of info....
Thanks and
Best regards
Benjamin

If it wires direct to the starter then it would bypass the NSS

It is a 1988 Corvette Z51 convertible.
The remote starter uses the existing wiring just as to simulate the ignition switch.
Therefore it uses the exact same path for starting as when I turn the key. The NSS is after the ignition switch, I tried it by probing the yellow starter wire.
With the key in start position, the yellow wire on the ignition switch is energized. Regardless of shifter position. The car only starts in N and P of course, so the NSS is behind the ignition switch. No new connection to the starter.
Thanks

BTW the alarm system is a Excalibur 1830. The instructions are not Corvette customized, they are general and just describe the wire hookup.
Other cars may therefore need the NSS hookup, but I don´t see the use in my ignition system. But maybe I should just connect it as a second safety...

( unless the unit needs it as a seperate control input ; not actually part of the starter circuit wiring)

Thanks for the schematic.
The remote start just needs to see ground on the NSS wire to enable remote start. As the ignition already has the NSS in its wiring I don´t think it makes sense to run another wire to the NSS circuit.
I´ll let you know when I am done with the system....

Only way to achieve what it appears you need is to bypass the NSS on the starter circuit and run a wire from the unit through the NSS to ground as is required

I installed a Viper system on my nephew's truck. It had a NSS option, but that was only for manual transmissions. Does this system have an option for manual vs. automatic transmission?

Hi,
the remote start works! The system has an option for eighter the parking brake or the NSS as a safety.
I grounded the NSS input of the remote start and hooked the rest up per description.
When in P or N it starts as it should, otherwise it just turns on the IGN and thats it as the NSS prevents starting anyway.
It works fine so far but maybe I will route a wire to the ECM and get the P/N signal there as a second safety feature.
I only need the underhood light input and install a couple of sensors regarding the alarm and I am done....
Thanks so far!

Would be easier to install a small pin switch that operates as soon as hood is lifted
rather than wait for hood fully open to operate the hood light mercury switches
( which often don't always work correctly)
Usually mount switch in hood latch area ( less wiring back to remote )
