You have it wired wrong. Since you're using the SPAL interconnect, you need a second relay to switch in the ground for it to work.

85 on relay goes to Blue/Black
87 to chassis
86 to chassis
30 to gray wire
87a no connection

In sorry I don't understand .. What do the number mean

99SH

Look at your wiring diagram. They are the terminals on the 2nd relay you need to purchase.

I don't see 85 86 87 on the sheet that I posted .. I defiantly don't understand wiring too much or the lingo ... Any way to be explained simply ? What do I need to buy to connect to the relay marked BB?

Take a look here for the complete wiring: https://webstore.spalusa.com/content...O-KIT_SPEC.pdf

Page 4 has the details for the 2nd relay.

Here's what I was thinking using the hardware you have now. In this configuration you don't need the 2nd relay. This setup will work given the relay coil does not have a diode across it. I emailed SPAL to confirm and will post here when I get a reply. You can try in advance if you wish:

I really appreciate the help .... So the only difference I have on the way I wired the harness and the picture is that my orange wire goes to the abs fuse ..
The picture says to ground it .. Correct ?
Why does my chart say switched ignition ?

99SH

Correct, ground the orange. Using my method you won't need a 2nd relay.

The SPAL wiring has you connecting the Orange to +12V switched and the Gray wire to the second relay. The purpose of the 2nd relay is to apply GND to the Gray wire when the OEM Blue/Black wire gets +12V (i.e. when the fan is triggered to turn on).

Either method should work. Again, I just emailed SPAL to confirm my approach is OK - specifically that there is no diode across the relay.

Hope this makes sense.

For reference here's the SPAL way to wire it per their manual:

These diagrams make a lot more sense !

I will try to ground the orange wire tomorrow and see what happens .. Worst comes to worst it won't blow anything right ? I hope I don't have to get another relay
