Just got a '03 Avalanche and I need to tap into a 12V accessory line near the radio and from what I can tell there are only 12V constant sources there. Anybody have the wiring codes for the new radios? Also wondering if there is a way to tie into the mute funtion for the onstar so I can install a hands free car kit for my cell.

Thanks

  Mine runs 145 to 158 ,95% of the time. ‘25 1500 with 5.3 and nht option. Wonder how long it will last? Wonder how much water is in the oil? Bought it in Oct 2024. This was today in south Louisiana.

  The exchanger is bolted right to the driver's side of the transmission. Would I go as far as to call it a heater? No. Does it aid in warming up the ATF to reduce friction as quickly as possible? Yes. What's the internals to it? No idea. Never cut one open. However, it's primary role is maintaining transmission temperatures once up to temp. No different than an oil to water exchanger for an engine oil cooler setup like GM uses on say 2010-2024 Camaro with V8, or 6.6 Duramax. Gas 10L80s (so 1500 truck with gas V8) have a thermostat in the valve body but not the cooler lines. 2019-current. 3.0 Duramax with 10L80 don't have a thermostat in the valve body. They have one in the lines going to the auxiliary cooler. 2020-current.
