scooby dooby doo Posted July 30, 2002 Share Posted July 30, 2002 Whats the pin number on the ECU plug that the ECU controlled fan plugs into? And also the shift light? (I think thats the 6th from the left on the middle row as you look at the plug with the wires away from you) HOOPY Link to comment Share on other sites More sharing options...
Al Crickmore Posted July 30, 2002 Share Posted July 30, 2002 I think I heard on another thread that it was 64? I'm sure someone will confirm or deny that very soon. Yellow/Carbon SL No.186 Edited by - al crickmore on 30 Jul 2002 16:18:48 Link to comment Share on other sites More sharing options...
scooby dooby doo Posted July 30, 2002 Author Share Posted July 30, 2002 not sure that there are 64 pins are there? 3 rows of about 12-14 pins I'd have guessed? OTOH I have been known to be wrong! (frequently!) This is for an EU2 engine by the way (actually for an Emerald M3DK ECU but its pin compatible with an EU2 MEMS) HOOPY Link to comment Share on other sites More sharing options...

Mole Posted July 30, 2002 Share Posted July 30, 2002 There is a recent thread titled "K Series engin temp question" that I think has the answer to the fan bit of your question .... (Sorry, havn't worked out how to do links yet but a scan down the list of topics should find it - it was last updated earlier today) Keep flying low The Mole @ the molehill Link to comment Share on other sites More sharing options...
Peter Carmichael Posted July 30, 2002 Share Posted July 30, 2002 Shift light. 2nd row, 6 in from LHS, looking from a socket's eye view with the catch on top of the connector between black-purple(5 in) and green-grey (7 in). Fan switch is 6 in from the LHS on the bottom row as described above between another unused pin and a grey (Lambda signal). *thumbup*253 bhp, up and running Link to comment Share on other sites More sharing options...

Paul D Jones Posted July 30, 2002 Share Posted July 30, 2002 Are you safe to drive the fan straight from this output or should it go through a relay not having this set up myself but worry about asking an ECU to run a fan when a relay cost less than a fiver and the consiquences of a blown ECU would be 10 times the cost I runmy rad fan from an electronic temp controller unit as seen on the fridges in Tescos etc these cost about 32 pounds and are programable to the temp they come on and off and switch 8amp also show the temp I have a stack and the temp prob for the stack is in the thermostate housing and the PT100 probe for the temp controler is in the water flow after the state so on warm up it always reads a lot lower then the stack or other way around so when the two eaqualise the state has opened and the engine is warmed up nicely.

Graham Perry Posted July 30, 2002 Share Posted July 30, 2002 I would use a relay as a fan can jam and as you suggest the consequences could be serious. Link to comment Share on other sites More sharing options...
