Location of Power Antenna relay LX450

[SucioP]

reviving an oldie….electric manual has this above the diff ecu and behind the amp on the passenger side. Pulling the bottom kick plate I can see the diff ecu but nothing behind the glove box where the amp used to be….is this thing behind the engine ecu?

I thought the locking ECM was in the engine compartment. Is it not? That's where the last LX450 I looked at was, unless I'm having a senior moment. Which is possible; I don't know how I'd know if I was...

Mr T says it’s above the Diff Lock ECU on the kick panel and it is…..way up there. What a PITA.

Hey folks! I'm in the process of troubleshooting my antenna now. The stock antenna does in fact work if I trigger it with alligator clips directly to the battery but absolutely nothing else. No auto up, buttons don't work so I thought...ok...must be the ECU. So I took it apart and what I saw with the relays is completely different than anything else I've seen online. Black ND relays instead of the white Denso's. Is this an attempted repair or did they ever come with these?

Hmm, looks like I may not have looked hard enough... found another thread with one that matches mine...

Not sure I want to start throwing money at this randomly. Everything "looks" good on the relay. Could a bad switch prevent both the auto up/down and manual from working? I don't hear any clicks or anything ever. The entire system just seems dead. It does have an aftermarket head unit.
