# Wiring the Hammer

![](https://help.feniex.com/hubfs/Knowledge%20Base%20Import/feniexhelp.zendesk.comhcarticle_attachments360007457134hammerwiring.png)

Step 1: Run a 16-18 gauge wire to a known good ground location (typically the negative battery post (12v-)) and splice the wire to the black wire coming from the Hammer.

Step 2: Run a 16-18 gauge wire to the positive battery post (12v+) and splice the wire to the red wire coming from the Hammer.

Step 3: Configure the Hammer to your preference. If tone adoption is required, a tone must be playing through your external speaker first before applying 12v+ to the yellow mode one wire. Once applied, the Hammers tone activation feature will be activated. 

Step 4: Test Functionality. If some functions do not work, please inspect your wiring for defects. 

Step 5: If all of your wiring is correct and the product is not overloaded, please contact Feniex Technical Support for assistance (1-800-615-8350)

For all other Hammer inquiries please see the appropriate articles or go to our website and research the literature for this product.
