highly Posted March 10, 2008 Share Posted March 10, 2008 I have a L28et that I'm installing an MS1V3 with EDIS. I've modded my MS for PWM Fidle and relay fan control. I was pondering swapping the wires in my MS-to-relay-board cable to put the fan output on the relay board's FIDLE relay effectively making it a fan relay. Besides the silkscreen on the board being wrong is there anything there that will turn around and bite me in my "third point of contact"? It puts my PWM FIDLE on a spare output without a relay socket and gives me a fan relay and is completely reversible at the harness (no soldering). I can post a rewired pic if needed, but this seems perfectly straightforward to me. Thoughts? Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted March 10, 2008 Share Posted March 10, 2008 The only major concern I'd see is that the relay board itself is not designed for the kind of current a fan draws. You'd need to use the FIDLE relay to activate a second off-the-board relay for the fan. Quote Link to comment Share on other sites More sharing options...
highly Posted March 10, 2008 Author Share Posted March 10, 2008 That's exactly the kind of thing I was looking for. A second relay would completely negate the point. Thanks! Quote Link to comment Share on other sites More sharing options...
speeder Posted March 14, 2008 Share Posted March 14, 2008 I've used the FIDLE Relay for fan control - I beefed up the relay contact circuit traces on the relay board with 12-guage wire, and of course cut and jumpered the circuit board to apply the correct signal fron the ecu to the relay coil. It's a good idea to use an inline fuse for the fan. Makes for a nice clean install. Quote Link to comment Share on other sites More sharing options...
