HI,

I'm installing a 2-Way alarm with remote starter (1990 240sx KA24E)

I'm been looking at FSM for hours trying to find a best place to tap into;

-Tach
-Neutral Switch (ground)
-Open Door Switch (ground)

don't want to tap into 3 different harnesses to get these wires or having wires running all the way across from driver side to passenger side ECU if I there is a better place.

Has anyone got good experience installing this things? any advice?

I will also need to wire few other things but I think I got that figures out
-door lock (driver side door harness)
-door unlock (driver side door harness)
-brake pedal (brake pedal lol)
-parking lights (steering column light switch)

Thanks for the input, well I couldn't get an answer so I just went a head and starting wiring stuff.

I connected the Tach, Door Open, dome light, Neutral switch to the gauge cluster harness behind the gauge cluster.

Actually there is no neutral switch wire there, but I didn't want to run a wire across to the other side. I'm just too lazy for that so I connected the neutral safty switch wire to the parking brake light on the gauge cluster harness.
Door open and Dome Light connected together to the door open light also on the gauge cluster harness.

Everything works fine, remote start, door open alarm and all that good stuff.

I know 240sx have 2 starter wires, one for the starter and the other is for ECU at start however in my case the car starts just fine even when the second start wires is completely cut off
