My preference would be to put all the cabling under a floor section rather than on/at the seat. Having the 8 pole connection on the seat will work but personally, well I want to be able to connect/disconnect each exciter/transducer in an easy way.
This then makes it simple if one gets damaged or if I want to swap what units an amp is powering for future or other location testing.
I got some of These
Might be handy if you don't already have some sorted
Agree on easy disconnection being a big plus point. If I have things correct, the NLT8MP has the large 6.3mm spade terminals. I would normally prefer soldering onto those but I might use crimp terminals for setting up and being able to move stuff around if needed.
Getting my hands on some exiters would be a good start. They aren't available at Amazon and they seem to have disappeared from the Dayton site. I'm wondering if they might have been discontinued? There is a seller on eBay but he charges £10 shipping per unit, no matter how many you order!
I was going to check out the link you provided but it doesn't seem to be working for me.
@jamescarruthers thanks for the multiplug links. Could be another nice and neat way to do it
