The 94-96 cars (correct me if I'm mistaken) have a separate cam angle sensor and crank sensor. Other years have them both in one unit on the passenger side of the head.
Here is where the CAS is located on these cars:
Closeup:
You'll first have to make a wiring harness to connect the 1gCAS to the cam angle sensor and crank sensor connector. (Link on how to make this harness:
RRE Instructions) step 1 is to cut the wiring harnesses for both. Cut them so you have as much wiring as possible to work with as you have to route the wiring around the back of the motor. Here's where I cut the cam sensor:
This is what the connector looks like for the cam angle sensor:
Here's the whole pigtail I cut off.
If you're still confused as to where these connectors are, they are both mounted on a metal bracket behind the motor by the firewall. Here's a picture of both pigtails mounted on the metal bracket:
These are the connectors that go to the wiring harness:
This is where I cut the crank sensor:
Once you make your wiring harness, you have to remove the plug on the passenger side of the head where you are going to install the 1g CAS.
To do this, you must remove the valve cover. Most of you have probably done this by now. Remove the spark plug wires, take out the spark plugs, and remove all the inside and outside bolts on the valve cover and remove. If you havn't taken it off in a while you may have to pry it open. Now would be a good time to get a new valve cover gasket set...especially if your old one is worn.
Here is the motor with the valve cover off. You have to remove this cap to get out the plug. Just take out the two 12mm bolts.
Here's the cap out and the plug out.
Here's the camshaft without the plug. You can see a slot where the CAS will go into.
Now, jack up your car. Take off the front driver's side wheel. Remove the plastic so you can see the crankshaft pulley. (I actually was able to do this without taking off the wheel, but taking it off makes it easier) Take a 1/2" drive (ratchet wrench) and turn the motor
CLOCKWISE so that the motor is TDC. Basically there are marks on the cam gears that you want to point towards each other. The mark on the exhaust cam gear (towards the front of the car) should face 3:00. The mark on the intake cam gear (towards the back of the car) should face 9:00. Shown below:
Now you have to set the 1g CAS to the right position. I can't seem to find the right words to describe what I want to say, so I'll do my best. But on the cas (shown below) the slot has one notched side. Also, the circle under it has a notch in it. You want to match up these notches.
Once you've lined this up, attach the cas to the camshaft in the slot at the end. Re-install the cap over the cam with the two 12mm bolts and torque to spec. Bolt the cas to the head. Make sure the bolts are in the middle of the slot for now. In the picture below, it's at the end, but you should have it in the middle to start.
Now go ahead and put the valve cover back on, and put your spark plugs back in. Now to use this cas you have to reverse the order of the spark plugs. From left to right, your cylinders are 4-3-2-1. The normal setup of spark plugs into the coil pack from left to right is 4-1-2-3. You need to reverse this so the order on the coil pack is (from left to right): 3-2-1-4. In DSMLink make sure "Invert CAS" is selected. I'm not sure how to do this without DSMLink, so someone please post up if you know what to do. Connect your wiring harness to the new 1g CAS and to the crank angle sensor and cam angle sensor on the wiring harness.
Now you have to set base timing again which should be 5 degrees advance. You will need to use a timing light. Follow proper directions for using a timing light. To adjust timing, simply loosen the bolts on the cas so you can rotate it. Rotate clockwise to decrease timing, and counterclockwise to add timing.
Now you're done!!
