    I'm buttoning everything up finally on my tear down and am shopping for a CAS. I'm just curious if it would be better to run a 1G blacktop with the magnus 1G in a 2G or run the 97-99 CAS?

    Did you put a 6 bolt motor in? If so I didn't think there was an option to run a 97-99 cas. So with that said 1G black top for sure.

    Reason being there is no crank sensor in a 1g motor. Both signals are pulled from the cas.

    It really just depends on if you have a 6-Bolt or 7-Bolt.

    If you have a 6-Bolt you need a 1G style CAS (unless you have something like a kiggly crank trigger kit.)

    If you have a 7-bolt, the CAS and crank sensor being separate is supposedly superior so stick with that if that's what you have.

    I have a 97 7 bolt in a 95 with a 95 ECU. I'm just un-sure of the connector difference in a 97 cas to a 95 cas. I haven't had time to look with the shift I'm on at work

    Personally, I would pick up a 95-96 CAS and matching intake cam gear and swap that on.

    To run the 97-99 you would need to splice a 97-99 CAS connector to your harness. I'm not sure about how the firing order would be though.

    To run the 1G CAS you need the special harness adapter or to hardwire one.


    If you run either 2g style CAS you need to make sure you also have a crank sensor in place as well.

    You would need to splice in the 97-99 CAS connector and swap the plug wires because the 97-99 CAS runs a non-inverted signal to the 95ecu. If you need a 97-99 CAS pigtail PM me.

    I'm confused can someone post a picture of a 97-99 CAS. Is it the same as the 96?

    Perfect thank you so there is there a difference between 1g and 97-99 CAS?

    Yes, 1G runs both the cam and crank signal while the 97-99 needs the crank sensor in addition to run. 1G is also adjustable, 2g isn't.

    Also the camshaft is different where the 97-99 bolts compared to the 1g CAS.

    I'm not going to run the 95/96 cas simply because its location is horrible and to remove it is quite the pain if the motor is in. Splicing in the 97/99 connector can't be very hard.. But this is also why i was debating a 1g CAS with the magnus 1G in a 2G cable

    I like the 1g CAS do to the fact you can adjust your timing.

    I've been researching and I'm pretty sure I'm just going to go 1g simply because it's easier with the RRE or Magnus harness and dsmlink being able to correct the inverted signal

    My vote would be for a 97-99 CAS/CPS due to the much cleaner signal versus a 1g CAS.

    I'm not against it I just don't know how to go about making them work on the 95 harness.

    Your existing CAS plug has 3 wires, right? Just lengthen them and put a 97-99 CAS plug on the end.

    Here's a 99 connector:

    The wires are black, blue, and red. I bet the 95-96 harness wiring is even the same color.

    Okay, and after that just swap my plugs and check the non-inverted box In ECM link and call it a day correct?

    Now its finding the connector

    with my experience i've had better cleaner reading with the Green top CAS versus the Black top CAS, oh and if you wanna save the outrages price magnus charges for that wire, you will find it in a 3000 GT. cant tell which model but it is in there;).
