Electrical Tech / Instrument Cluster Illumination
Hey everyone ,

1987 mercury cougar
full digital dash

Problem I'm having is the Instrument Cluster back lights do not light up during the day (well its very very dull)  unless the head light switch is on,

at night the Cluster is bright and normal with auto lamp working 

all other lights in car and external work,

i have replaced all the switches that have to do with the lights, dimmers and auto headlight , the auto sensors on the rear mirror and the one under the center dash hoping to fix the issue,

is there a relay i am missing ?

could it be a ignition switch problem starting or ...



thanks

Electrical Tech / Re: 20th anni a9l swap
hey softtouch


thanks for all your help , i just got to the wiring today ,only -7C in the garage up here in Ontario Canada

pin 30 did have voltage on crank.

i did all the pin changes for the mass air and h.o swap

i ended up wiring my clutch switch plug #1 in place of the old NSS (auto) so it will only start with clutch in.

i cut pin 30 at the ecu harness plug and wired in parallel with clutch plug #2 and the NGS on top the t5 and connected them to pin 46

it now starts, idles and drops idle a little when in neutral or clutch is presses like its suppose to

Sorry it took so long to get back and thank you

Electrical Tech / Re: 20th anni a9l swap
my clutch pedals didnt come with that one , so i figured i would just not use one. if i needed to turn it off i would tap the brake or use the steering switch

Electrical Tech / Re: 20th anni a9l swap
just checked the switch , both plugs are open till the pedal is pressed  then they close, and they share no electrical connection

Electrical Tech / Re: 20th anni a9l swap
the pedals are out of an 89 mustang

the switch i have has two plugs like the turbo coupe but have to add them to my harness

one plug for the start neutral 

one plug for ecu pin 30 parallel with ngs connecting pin 46

Electrical Tech / Re: 20th anni a9l swap
Hey thanks for getting back to me

i plan on using the harness in the car to mod into mass air

i was wrong , i think i only tested for for voltage at pin 46 not 30 while cranking

i did run the a9l in my old 87 cougar with auto trans and h.o mass swap with no problems

yes the t5 has a ngs on the top of it 


i know the only differences in the car harness and spare harness are 20th anni options and ls options

this is what i was thinking .... how does it look ???


this way pin 30 never touches ignition just two switches and back to 46

still using clutch pedal for start

and seat memory still gets signal from clutch ?

i see two switch plugs on the clutch pedal i guess one for start and one for idle/no load,,, i dont have the cruise switch on my pedals

Electrical Tech / 20th anni a9l swap
Hey Guys

I'm at that point in the build where its wiring time

1987 cougar 20th anni

89 engine 5.0, t5 and a9l computer, mass air

I've been searching and reading and reading and searching for info on how to wire it up so pin 30 and 46 are cool with each other

the closest I've come to figuring it out is

How to kill, repair and not kill again an A9L in an 88 and possibly others  by CougarSE

memory seat module by james cassity

and some other guys on the mustang forums

a lot of help and info from facebook and instagram

i know i have no voltage to pin 30 when in run or crank so i can get away with not doing any wiring at all but would love everything to work like it could have been stock

i traced the wires out on a physical harness ( 87 cougar ls auto)  from ecu to end points for both pins

My plan was to cut the brown white wire (30) at the ignition switch, bypass it and wire them in parallel with the clutch and ngs , then return them to pin (46)

i was going to splice the red  blue wire between the ignition switch and nss switch wiring and run them to the other clutch switch  and connect them to the white pink (ngs) to complete the circuit for starting.

in my head and spare harness ( cougar ls 5.0 auto)  it was kinda making sense till i got in my car and noticed the memory seat wiring plug had an extra wire instead of ending at the plug , now i am lost.....

someone please steer me in the right direction , ill read anything as long as it will work

my other option was to cut the brown white wire (30) just as it gets into the car before it splits into two leaving the brown white wire connected to the ignition and power seat plug. and add the clutch/ngs wiring at that point


lost lost lost

home made diagram was for me to see it as i was tracing and to kinda help maybe someone else has done this before

Drivetrain Tech / turbo coupe vs ls prop valve
hey guys

 just starting my tc axle swap today on my 87 cougar and was thinking, would it be easier to swap the internals from my tc prop valve to my cougar instead of adding fitting adapters to go one size up or running larger lines to the back?

i know i still need an adapter from my stock lines to the axle line.

anyone know if the valve bodies are internally different other then that the rear brake fittings are larger

Thank you

Drivetrain Tech / Carrier and pinion bearings
stupid question and trying to save money, i have an 8.8 tc rear end with 3.55 gears
i wanted to replace the clutch plates and all the bearings before i swap it into the car, will i have to re-shim the pinion and carrier if i just replace the bearings with oem ford?

trying to get my rear in shape for spring

thanks

Electrical Tech / Dome light wiring
1987 20th anniversary

found some mice nests in my back seat and blower motor, pulled everything out and am noticing my dome light is not working anymore.the light does not work with the door or manual switch's but the lights under the dash still come on when the door opens.

anyone have a idea if there is a plug under the pass side dash i may have missed or if the light is grounded through the front seats seat belt assy that i removed for cleaning.




Thanks

Drivetrain Tech / AOD high shift point
ive owned the car for almost eight years and insurance was killer for someone my age at that time, so i dont really remember if the trans was always like that because ive never legally driven it ( just around my neighborhood) but im 25 now and insurance is cheep

Drivetrain Tech / AOD high shift point
its under a light load i would guess , if i stomp it she will fly but still takes a second or to to realize and change gears.
 i guess im just looking for a crisp response when i touch the gas peddle not a delayed reaction.
i was under there in the fall redoing my shift linkage ( long tube headers and column shifter) and the cable seamed to be in working order pulled and retracted fine.
