I never tried it with the hood open, so this is a guess.....
On my '98 with a dealer installed VIP alarm, the chirper was ty-wrapped to the wiring near the brake booster......it was about the size of a spool of thread....................I think......
I think the chirper is associated more with the remote pwr door locks circuit because without alarm, the chirper goes when locking/unlocking....
As a side note, I just had my 3000 installed in my '05 RAV, but it only unlocks drivers door because the '05 requires two pulses to unlock all doors........locking is fine.......
Anyone know how to reprogram the 3000 for two pulse unlocking??? :?:
