RS addon/ no work help!

96 accord lx, it remote start when i manually ground it. but when hookin up to the unlock wire nothing comes on.

please help

i hooked to lock wire, do you have to use the unlock wire? i got the wire from the 3 pin gray plug that runs to the factory keyless unit.  when i tested on the lock wire it jumps up couple after pressing lock.

i think it is RES remote start add-on

i havent try the relay to trigger the RES add-on. but when start it manually by grounding it, it cranks normal but doesnt stay on for long, last only 2-3 sec then off and then it try to crank again.

i havent hook up the tach wire, it say it's optional to the neg side of the coil. if i were to hook this up, would i just hook it up to the blue wire on the injector with 2 wires on it.

why does it say neg side of the coil, is that mean its a neg pulse. am confuse about this. but i test it using positive.

this is what i did to test my tach wire, dmm set to ac -200v/ black probe to ground and red to the wire. it reads at 32 and steadily jumps up as reving on the gas.

but the manual say "optional (-) coil tach input. do not connect unless the remote start fails to retry if the first crank attempt fails. connects to the (-) of the coil. keep away from high voltage wires. if used, set sw5 to 'off'.

so what i have right now is volt sensing, and if i use that wire and sw5 to off then i have it in tach mode?

i dont understand why testing that tach wire shows in 30s volts. it increase in volt when i rev on the gas. i got this cheap DMM, i dont know if it matters? i did put it in AC mode testing.

any input to this would be great. and thanks a lot J Rilla you been very helpful.
