Hi guys

I installed bulldoge remot starter  delux 500 in Lexus 1997 Lx450  iconnect all the wires exept the tach wire becaus i cuoldnt  located the wire  the car cranks and stops and dosnt start again  and every thing stays on  and thr lcd transmeter shows the car has started . what i know if the car sometimes dosnt start first time should start  2th or 3th time . so anyone can help me please.  

If you can't locate a tach wire your alarm should be able to learn a fuel injector control wire. My wife's lexus I found the Tach wire under the dash. It was an orange 22awg wire.

If that fails then the next best thing is to garb a fuel injector wire. If you pull apart the electrical connector to an injector you should see 3 wires. 1 will be +12 volsts, 1 will be groud, and 1 will be the contorl wire. Thats the wire you want.
