replacing a Bose for a Pioneer system.

Cant you just use the hot that powered the Bose headunit? Even though the Bose speakers are all individually powered, the headunit needs power too.

Places like Crutchfield sell premade conversion harnesses and I don't think there is a need for a separate hot.

At least as far as I recall from the Bose removal in my 85.

Are you changing the speakers also? That new headunit will not be real happy with the 1Ω Bose speakers or the integral amps.

Correct. Unless he gets the adapter box that allows for non-Bose headunits to work with Bose speakers.

Good point.

i already changed the speakers and ran new wires. I will not be using any Bose wiring. I just need to find the hot.The Pioneer harness will do the rest.

Someone with a wiring diagram for a 93 will have to chime in. I am sure the original headunit had a hot as well.

On my '95 and many other vehicles the Orange wire is 12V battery (hot always) and the yellow is the 12V that's switched from the ignition. I'll bet yours is the same.

You nailed it. The orange is constant hot and yellow is ignition hot. Thanks for the help. Time to finish it up.

I am not sure if this is what you did or not but why not buy the adapter for the factory harness, connect it of course, and then only connect the orange and yellow from the adapter side to the pioneer harness? So you basically leave the speaker wires from the adapter harness alone (cut or tape them off) and just not connect them to the speaker wires of the pioneer harness. Then just use the speakers wires from the pioneer harness and run those straight to your new speakers?
This way the only connections you are using from the pioneer to the adapter to the factory harness is the orange and yellow. Might save you a few less crimps or some soldering and save you some energy for all the bending and twisting lol.

Maybe I have this wrong myself but I think that might work.
I am almost to that point in my set up and am also going pioneer. Which HU and speakers did you go with?

I purchased the Pioneer radio and plan to use the PAC RP5-GM11 Wiring Interface for the steering wheel and Bose interface.

I'm trying to find out where the Sirius XM factory installed antenna wire is located.
Rather not hook up the antenna that comes with the new XM tuner if I can use the factory one.

Can the factory xm antenna be used with the SXV3000 tuner?

Rather not run a new XM antenna if not needed.

Wrong!

This is an older thread. GM has used the same radio/cassette/cd player wiring for 50 years. This Corvette Owner only had to look for Chevrolet auto stereo wiring colors. Here is the wiring colors you will find for a radio installation. If his Bose system used different colors, these wires are still located in the factory radio position.
What to Know about GM factory stereo wiring:

• The 12V battery wire is yellow, the accessory wire is red, and the dimmer/illumination wire is orange with a white stripe.
• The right-front speaker wires are gray, left-front speakers are white, right-rear speakers are purple, and left-rear speakers are green.
• Ground wires are black, antenna wires are blue, and amplifier wires are blue with a white stripe.

Note: All other vehicles use a different color scheme. I will be glad to post if you cannot find the correct color codes on the internet. DS

Just a side note. The head units in the corvette with the Bose system are not Bose. They are GM factory units and have Bose amps and speakers. If you plain to retain the Bose system do not purchase a high out put head unit. This will over load the Bose amp and cause premature failure. You want an RMS value of 20 watts or less and a maximum of no more than 50 watts.
