I have a 1988 Eldo, my stock head unit was a Delco 1.5 DIN unit. The new head unit I have in now is a DHD NTX-8024 single DIN mount. The auto parts stores i went to told me there was no 1.5 DIN > 1 DIN harness available and to just leave the half DIN unplugged and tucked away... I have no idea what it's purpose is but it's 4 wires on a 5 wire head, a black, a dark grey, a grey, and a lilac with a black stripe. there is a blank space between the lilac/stripe and the other 3 wires. Not only is that unplugged but the radio-specific harness from the head unit has two wires for "illumination/backlight" that the gm generic harness they have me using doesn't include, so those are tucked away as well and now I have no backlight on my head unit when it's not turned on (yeah squinting to see your clock sucks). I looked at the generic GM harness in my dash today and found there is a fourth hookup spot open but no wires to it... (I have in it the 6 pin white connector, the 4 pin blue connector, and the 4 pin white white connecter) The fourth blank hookup spot is a 5 pin spot but there arent any wires there, just the empty holes for them. The one that isn't plugged in (the half DIN) is a black 10 pin connector (2 rows of 5). Does anyone know of a 1.5 DIN > 1 DIN conversion harness? or at least a way to wire this up so that i can see something without having the head unit turned on?
I'm not sure if this is related to the harness or not but my bass sounds "squishy" It reminds me of when you place a sopping wet sponge on a table and push down on it repeatedly with the palm of your hand... that sound that Jeff Foxworthy makes when he does the Jello joke.... You guys know what i mean it's hard to explain. I've heard this comes from either your head unit not being powerful enough or some people blame it on the unconnected half DIN. Which is it?
