Le NA in vendita -Parte 2-

[Pepi]

Non so nelle 115cv, ma nelle 90cv mi pare una modifica comune. Magari le tanto vituperate 90cv sono già predisposte, nonostante la gravissima assenza del cp

Al più si tratta di portare la corrente al motorino e il segnale dalla radio, ben 2 fili. Credo sia più semplice di mettere un turbo nel vano motore, tu che dici? :haha:

eh non lo so sai...

I'll be attempting something similar in a few short weeks. I have a 1990 (before the powerantenna), and I have the PowerAntenna from a 1994, with the clear fuse box attached to it. I need to add the cable from the radio - trying to get a used one. From another thread, I have the Pinout of the cable (Jeff's comments):

Q1. What are all the wires for on the NA unit with 4+ ground?
A1. First, be aware that the wiring colors within the Miata's powerantenna connector are not the same wiring colors as the car's. They are also inconsistent from sample to sample, including too for Miata power antennas found within single Miata years.

Nevertheless, corresponding connections from one sample of an actual OEM powerantenna connector are:
1) blue/red
2) green/white
3) black/yellow
4) blue/white
5) The powerantenna's black wiring (pre-attached to its metal mounting) is for grounding to car body metal ground.

Q2. Might you know what the 5 wires connect to, 4 and a ground?
A2. The car's four wiring runs, and ground, are:
1) constant 12V power, 10 amp ANTENNA fused (red/black wiring)
2) radio control signals (light-green/yellow wiring)
3) ign2 signal, METER fused (black/yellow wiring)
4) ACC signal, CIGAR fused (blue/black wiring)
5) car body metal ground at antenna mounting (no car wring)

Q3. What is my best option from a performance, price, installation ease perspective?
A3. For powerantenna, that'd be an OEM NA Miata radio and a pre-97 OEM Mazda Miata powerantenna for a 1996 Miata. An OEM NA Miata radio with a NA Miata OEM fixed antenna, provides better radio broadcast station reception capability. Expect aftermarket radios to provide reduced radio broadcast station reception capability.

FYI- also needed is the little in-line 4-pin (not the same 4-pin connector as the antenna's 4-pin connector) two-fuse fuse box, that installs in the trunk, that fuses the powerantenna and rear window defogger.


And from another thread, I have to reinforce the base of the antenna to not deform the sheet metal of the thread. I'll use the bracket at the base of the antenna to lock it down.

I think that's everything - I want to play with the pinout to get the antenna up, then test the output of the radio to determinine if its a momentary contact or a switched contact. I have not seen the antenna switching definitively defined, but the descriptions imply that it is a switched contact with an interposing relay.
