	Most of the tedious work is done now; all we need to do is connect the relay and 9v batteries. First, locate the wires that you removed from the motor's terminals. Solder them to the coil side of the relay. Next, solder the 9v battery leads in series, then connect one of the wires to the switch side of the relay, and the other to the solenoid. Lastly, connect the other solenoid wire to the remaining switch lead on the relay. All that is left to do is to mount the antenna, and you are done.

To get the remote to fit in the phone, I shaved off part of the circuit using a dremel, then wired the forward button to the end button on the cell phone key pad. Lastly, I modified the circuit to accept power from a car key fob battery; which is significantly smaller than a standard 9 volt.		The remote in its stock form will work just fine.

	~~'''~~...~~Other Info~~....~~'''~~		This is a very basic R/C circuit, and is thus prone to picking up interference. This system was designed to be used in the woods; acting as a remote detonated mine. You must remember that this cannot be used in a modded sprinkler valve unless you bough a separate solenoid valve to pilot the sprinkler valve (such as a small 1/4 NPT solenoid valve or similar). If the device goes off as soon as you turn on the power switch, the diode was inserted in the wrong direction. This is simple to correct. Simply unsolder the diode, then turn it 180 degrees and solder it back in place. The R/C receiver is relatively poor in quality, and in my mine it is paired with about 20ft of antenna wire, which would normally be wrapped around a nearby tree to give it an effective range of over 100ft. If you plan on using this underground (in the case of my mine), encase all of the electronic components in hot glue to prevent them from being damaged by water. Lastly, if the device seems to detonate randomly, and external radio interference is determined to not be the culprit, the issue is likely the antenna. Ensure that the antenna wire is not making contact with any metal components of the circuit board.

			'''Alternative Parts:'''

			The 1-channel R/C Car transmitter / receiver pair can be replaced by several other systems.

			One possibility is a remote car unlock R/C setup often available for cheap from electronics surplus places. For example, [http://www.allelectronics.com/ All Electronics] sometimes has a "keyless entry" system with two fobs (like a car uses) and the receiver. It'll easily handle the current required for a solenoid or a relay; [http://www.allelectronics.com/cgi-bin/item/RC-10/search/KEYCHAIN_REMOTE_CONTROL,_12VDC_6_AMP_.html CAT# RC-10] for $18.75. A little pricier than a cheapo R/C but you wont need a relay since this will handle 12V at 6A directly. [[Image:RC-10.jpg\|Car remote (R/C) entry FOB system]]

Another possibility is to use the pager function found on many cordless phones. With a little creative scrounging you can often get an unused cordless phone for free.
