Well, been meaning to get this done for a while. Didn't want the hot start kit from Bosche or the Ford relay, so I found one on line that I liked.
Installed the relay on a small bracket on one of the mounting screws for the relay board. Ran a new small yellow wire to pin 6 of the 12 pin connector and a brown ground wire to the bracket . Ran two 12 ga. wires fron the relay to the solenoid with the hot wire having an inline water resistant ATC fuse holder with a 30 amp fuse. Put some heat shrink around the normally used large yellow wire to protect it. On the solenoid side used tape to protect the connector that used to be hooked to the solenoid. This relay uses 140 mili-amp so not a very large inductive spike to worry about, but I installed a supression diode across the relay coil anyway. Also put a larger one across the solenoid coil at the relay ( 87 to ground). This supresses the solenoid coil inductive spike to protect the relay contacts. here are a few pics, and a link to more info: http://www.google.com/url?sa=t&rct=j&a...eg_6KDxZdKYQYGw This is the aeroelectric link Oh, I tested it several times and it works just fine. Tom Edit: changed back EMF to inductive spike, sorry if this confused anyone. Inductive or transient spike is the correct term for what is happening here Attached thumbnail(s) |

With no forum to spend time on, I found time to finish up my generation 2 starter relay with bump feature and got it installed. It works great. Key off and just push the start switch on the relay panel for a bump. Pics show installation on the relay board, then installed on car, and finally stealth mode. With cover on, it is not noticable that there have been any changes made except for the extra wiring harness! Don't know how many would even notice that unless they were looking for it.
