[E30randy]

Hey I'm in the final works of my m52 e30 swap and I've got these 3 relays(2 light green colored and one pinkish red) connected to a red cable and I don't know where they connect if there supposed to go on the engine or on the body side please help

That red cable is normally connected to the fuse box providing +12v from battery to the cars wiring harness. The other end of that cable dhould be connected to the +12v from battery? Is it? If yes, then you don't need to connect that anywhere in e30 swap. The relays are dme relay, fuel pump relay and unloader relay.

Orange Relay is secondary air pump.

Orange Relay is secondary air pump.

You may be right.We don't have those here so I have never seen that. Normally there is only 2relays, but is some harneses the unloader relay is also included.

Orange one is secondary air pump.
The other two relays are the main relay and the fuel pump relay.
The other odd relay all by itself (not in your pictures), would be the unloader relay
