It’s leaking from under the car. It’s the gas tank but I’m not sure where. I haven’t really looked.

I smelled burning oil when I stopped today. The oil was near the bottom of the ok marks. I topped it off with 5w-20. I got pictures of the dash lights.

I still haven’t fixed anything. Here’s some pictures. Alarm System is a new light.

Alarm system warning might be because of a faulty alarm module, had that problem on a V70 I used to own. It also affected the operation of the sunroof. The module is located in front of the passenger front wheel, remove the wheel liner and you'll see it.

So I should change it?

My first 2 concerns are the oil burning and the gas leak.

1. Should I drop the tank and look for cracks? How do I do that and how do I fix a crack I find?

2. The oil burning is a leak somewhere under the hood. BMWs are known for valve cover gasket and oil Filter housing gaskets failing on all used cars. What is probably leaking on mine?

If the PCV plugs, cam seals push out on Volvos, which cause big oil leaks.

A used gas tank I still best option for the leak. Once you drop it, you probably will find it’s just a hose repair, though.

do the "glove test" For PCV pressure. the oil light points toward the sensor being bad or disconnected

Guys I really like Crutchfield. They make installs really easy on just about everything I’ve worked on until this car. I even bought the ready harness service. My install on the spyder took maybe 30 mins using the ready harness service.

My wife wanted a radio with GPS and a backup camera. I’ve got the camera installed and wires ran. I’ve got the gps antenna wire and microphone for the hands free radio tucked and ready to plug in. Then I tried to hook up the wire harness. I’ve got a antenna hook up, 2 circle connections?, and a green connector from the factory. From Crutchfield I have a green big connection, Gray big connection, antenna adapter and that’s it. The radio has its own inputs for the gps and microphone and all the back up camera connections. The green connector fits to the factory but only has power wires. The gray one has all the speaker wires. Noting will hook up to the gray wire. YouTube is worthless on volvo aftermarket stereo installs.

Please help.

Here are a few pictures of the install-
The green connector with the most wires is the OEM. The green with few wires is from Crutchfield these wires are 12+, ground, remote on, power antenna. The gray is also from crutchfield. These 2 long leads are for the backup camera. I don’t understand what these multi-pin connectors on the gray and black cables are for.

I also have a picture to show where I put microphones and GPS.

Please help me walk through this and I will document everything and give you the credit.

Will this work for a 2004 v70?

The YouTube video above doesn’t seem to work out the same. I got a bunch of wires under the seats but I’m not sure what they’re for and I may have just wasted time pulling them out.

Please someone help. I haven’t found the answers in the search yet.

Dale at Crutchfield helped me out. I have the wrong harness. They’re sending the right one to me. https://www.crutchfield.com/S-qUfHuYECg ... s&skipvs=T

I’ll get it all together and post pictures. Notice the din has a blue and black and so does the green harness. These colors that match get connected and once everything is plugged in it should work. I have the green one but I need the din to rca. I’ll have it Thursday and get it all terminated.

After my wife gets back from running errands I’ve got to put the parts back together under the seats.

To have the backup light come on automatically I need to tap the reverse lights. I have a red wire on trigger wire near the radio that I need to hook up and 3 wires in the back.

The 3 wires I need to tap at the back of the car are a reverse wire trigger, reverse + and a ground. It’s in the back hatch and the wires are loose of the harness near the grommet that goes back into the car besides the left hinge.

Can you help answer these questions-
1. What color wire and where for the reverse trigger in the front?

2. What color wire and where for the trigger wire in or near the hatch?

3. What color wire and where for the reverse + in or near the hatch?

4. Can I tap into any ground for the backup camera ground wire in the rear or should I attach to a chassis ground? Where would you suggest?
