airmike Posted May 17, 2013 Report Share Posted May 17, 2013 I am finally getting to resume my head gasket repair on my sts. After 2 years I am spending considerable time trying to find where things go. Well here is a hose that was found in the under hood fuse block. Notice the black hard plastic hose coming out of the orange wire bundle on the very left of the pic. It ends under the connector in the center of the pic. It can just barely be seen next to the bottom edge of the housing. This photo was taken as I was taking things apart back when. I don't understand a hose even being inside that housing.

Cadillac Jim Posted May 17, 2013 Report Share Posted May 17, 2013 Is this the 1999 STS or the 2006 SLR_V? -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

airmike Posted May 17, 2013 Author Report Share Posted May 17, 2013 barczy01-----that response is a little vague. If someone tells me the oil filter is "nothing, just disregard", I don't think I will, if you know what I mean. Link to comment Share on other sites More sharing options...

airmike Posted May 18, 2013 Author Report Share Posted May 18, 2013 rockfangd do you have any idea where it should be connected under the hood? It just ends right there in the fuse block housing? Link to comment Share on other sites More sharing options...
Logan Posted May 18, 2013 Report Share Posted May 18, 2013 Sometimes those are added to a harness to beef it up.....or the harness may have to be routed around a sharp corner somewhere or pushed thru a hole during vehicle assembly. I don't know if that is the case here...it looks like a pretty beefy harness already.

Cadillac Jim Posted May 19, 2013 Report Share Posted May 19, 2013 Vacuum hoses usually are thick neoprene but not hard plastic. Also, I don't know of vacuum hoses included in wiring harnesses. The photo looks like the back of the underhood fuse block, which is different from my 1997 so I don't have any direct information on what is what there. The connector that partly covers the end of the hose actually looks like it houses three inline old-style fuses, although the wires on one end look like the go to fuses in the right hand block. The big wiring harness that the tube comes out of looks like it has two wires that go to the Maxifuse block or to circuit breakers, a big red one (a ringer for an always-hot maxifuse) and what looks like a large orange-white wire. Some of the wires coming out of it are pink, which are usually switched ignition wires such as "Hot in start and run." So, it probably goes to the ignition switch, with possible branches at the steering column, heater/ac controller or elsewhere near the driver's side. I can't see running a tube from under the hood to the cabin, so it must come out somewhere under the hood. Check the cruise control for a servo pressure release vent. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Logan Posted May 19, 2013 Report Share Posted May 19, 2013 The 3 way plug...is not a fuse holder. Its a GM weather pack connector. The attached pic is similar but not exactly the same style.
