    2015-03-03 17.15.03.jpg So I've been trying to figure out what this part is. I'm guessing is a resistor pack but I'm not sure. Any help in identifying this part would be greatly appreciated. Thanks

    You are correct. There are various connection formats. Check the datasheet for this one. RES0180 looks like the right number.

    Couldn't find a datasheet on it.

    looks like its a resistor block, try reading the pins with an ohm meter.

    All pins seem to be connected together. Every pin seems to have a different resistance in respect to one another, its an odd first one for me.

    usually one pin is the common, youneed to remove it for measuring.

    Resistor packs come in two verities. You may find nine independent resistors of the same value or all resistors have a common connection which are frequently used as pull-ups.

    It's a resistor pack, all right; made by CTS. I'm guessing it's a 16-bit SCSI terminator: one pin for GND, one pin for VCC, and 16 data lines.

    That's my guess, anyway...

    Can you show us the rest of the board? What is it out of?

    Its out of a car alarm module. It connects to the reciever for the key fob.

    I think there are only a few limited configurations for standard resistor networks. You could use a datasheet like this one, and using an ohmmeter, determine which of the schematics matches your network. Is it possible to unsolder the part?

    I did as you suggested and found (i hope) the configuration of the pack thanks everybody's help.
