12 VDC Automotive 5-Pin Relay SPDT 30/40A Bosch Type
Every site is telling this is the correct relay for a 5 pin, 12v. (0511 YL049) The diagram is the same on every one, BUT MINE. Mine shows component (resistor like) drawn from contact 86 to 85, connecting them?
The resistor is used to reduce spike voltage when the relay is de-energized. The purpose of spike reduction is to protect sensitive electronic equipment.

Hi I have a 1994 plymouth voyager will this fit and will it help stop the flickering lights when I'm pushing the sound up , thanks.
If the lights are flickering due to being close to the alternators max power, then a relay will not help. You might try a stiffening cap instead.

Is there a diode and resistor inline ; inside houseing. Kh
No. Just a coil and 2 sets of form C contacts.

I'm activating this relay with 16 Volts. Is this safe or shorten the life of the coil?
It will shorten the coil's life a bit, but probably not much. This relay is rated for automotive use, and a car's electrical system runs at about 14V when the car is running and the alternator is charging the battery, so 16V isn't too much more than that. How much it will shorten the coil's life is hard to say.Something you could do is put a resistor in series with the coil, to drop the voltage that appears across the coil to 12V. As I mentioned in my review of this relay, the coil's resistance is 90 ohms, so if you want to drop from 16V to 12V (that is, if you want the resistor to drop 4V), then use a resistor of 30 ohms. However, 30 ohm resistors aren't always available, so something close would work: 27 or 33 ohms would be fine (you don't need to be very precise here). As for the resistor's power rating, it will consume about 0.5W, so make sure it is rated for at LEAST that much power (standard resistors are only rated for 0.25W).
