Hi,
Does anyone have a definitive pin out for the 409 fuel pump relay? I need to retro fit one to an 1.8T (AGU) conversion in a Lotus Elise and the pin labeling on the wiring diagram (Haynes, admittedly) is different to that on the relay?? Some I have managed to work out myself by a process of elimination but I am missing some critical ones.
What I have so far is as follows...
Relay pins remaining are, 4/15 and 1/MOT, also I seem to have 8 pins on the diagram and only 7 on the relay????!
Any help greatfully received! I have been trying to find the answer online all day!

What I have so far is as follows...
| Haynes diagram | Relay pin | Function |
| S3/1 | 9/TK | Door switch input |
| S3/2 | ?? | +12V on cranking |
| S1/1 | 31 | Earth |
| S3/5 | 3/C | Crash input |
| S3/3 | ?? | +12V when ignition on |
| 502 | 2/30 | +12V Permanent |
| 504 | 8/87 | +12V feed to pump |
| S3/6 | ?? | Signal from ECU (T80/4) |
