question on driver seat connectors or harness

mr toro · 08-12-2011, 05:43 AM

i am attemting to put in a set of c4s seats into my 986. Passenger side is working just fine. On the driver side there is only the black control box and no female connectros to accept the male connectors from the chassis.

My question:

On a 996 driver side does the chassis wiring connect into the black box or is the particular seat that I got missing an harness. If there a missing harness it does not look like anything was cut off by the previous owne.

thank you

There are several different models of seats for both cars, each car was wired to match the seats it shipped with. Seats from another car may bolt in, but car may not have the harness to match.

How laborious and costly is a retrofit? Should I just look for boxster seats?

There were several "levels" of seats; manual, power front/back only, power everything, memory/no memory, etc.) Each had is own harness due to the number of seat control switches, and none of the harnesses can be retrofitted; you have to replace the entire interior harness (read big bucks). The seat mounting itself is the same in both cars, it is the wiring that creates the headache…..

If you read through the wiring diagrams, you can certainly make it work but it will be some work and wiring. Put a set of 996 full power seats in a 944 many years ago which was not equiped with power seats. You CAN hardwire it with terminal 30 and the seats would be operable with or without the ignition on. You can also install a relayed power supply tapped into a terminal 15 switched power and run a terminal 30 lead for relay supply, output to consumer.
